The Power of Stack Sizes: How Tracking Can Transform Your Poker Game

Most players track one number: whether they won or lost. That’s like a football team only checking the final score and never looking at the game film.

The players who improve fastest treat poker like a data problem. They don’t just know that they lost. They know at what stack size they tend to make mistakes, when in a tournament they usually bust, and how much fees are really cutting into their results.

This guide shows you how to build a simple, data-driven tracking system centered on stack sizes, and how the numbers you collect can transform the way you play.

Why Numbers Beat Memory

Poker memory is unreliable. We remember the painful bad beats and the thrilling big wins. We forget the dozens of small decisions that actually shaped our results.

Tracking replaces feelings with facts. When you record your results by stack size, tournament stage, and format, you stop guessing about your leaks and start seeing them clearly.

Here’s a quick example of how that shift changes things:

What You Feel	What Tracking Might Reveal
“I always get unlucky late in tournaments.”	You bust most often with 12–20 big blinds, usually after calling a shove too loosely.
“I’m a winning player overall.”	You’re winning at one buy-in level but losing at another once fees are included.
“Short stacks are my weakness.”	You’re actually strong with under 10 BB, but you wait too long to shove at 15 BB.

These are illustrative examples of the kinds of insights tracking can reveal, not results from real players.

Part 1: Track Your Real Results, Including Rake

Before tracking anything else, make sure you know your true results. That means including every fee.

Fresh 2026 Data: Rake Is Changing

A Card Player analysis published last week compared tournament rake across buy-in levels from 2015 and 2019 against 2025–26 events. It found that rake has risen over the decade, but not evenly across all stakes. Some of the key numbers:

• The WSOP Circuit $1,700 Main Event has held steady at around 10.88% rake since 2019.
• The WSOP Circuit $400 multi-flight event has dipped slightly, from 18.08% in 2015 to 17.50% today, one of the few small-stakes events where rake hasn’t gone up.

The analysis also raised an interesting point: because rake takes a smaller share of bigger buy-ins, and player pools at higher stakes aren’t always much tougher, some players might theoretically post a better ROI moving up from $500 events to $1,000 events.

What That Means in Real Money

Event	Buy-In	Approx. Rake per Entry	Rake Over 20 Entries
WSOPC $400 multi-flight	$400	About $70	About $1,400
WSOPC $1,700 Main Event	$1,700	About $185	About $3,700

Calculated from the rake percentages above; actual fees vary by venue and event.

The $1,700 fee is bigger in dollars, but the $400 event takes a far higher percentage of every buy-in. If you only track your cashes and forget the fees, you can easily think you’re winning when you’re actually breaking even or losing.

These events are drawing big fields right now. The WSOP Circuit Main Event in Austin that wrapped up this week was a $1,700 buy-in, drew a record 2,090 entries, and was won by Eric Chang for $433,670.

What to Record for Every Tournament

• Buy-in and fees (including re-entries)
• Number of entries
• Your finishing position
• Your prize (if any)
• Net result (prize minus all buy-ins and fees)

Over time, calculate your ROI (return on investment):

ROI = (Total winnings − Total buy-ins including fees) ÷ Total buy-ins including fees × 100

This single number tells you more about your real performance than any individual result.

Part 2: Bust-Out Analysis, the Most Revealing Stat

If you only add one new habit, make it this one. Every time you’re eliminated from a tournament, record your stack and situation right before the hand that busted you.

What to Record

• Your stack in big blinds at the start of the hand
• The stage (early, middle, bubble, in the money, final table)
• Your position
• How you went out (you shoved, you called a shove, a post-flop pot)
• Your hand and your opponent’s hand
• Whether you’d make the same decision again

What to Look For

After 20 or 30 tournaments, patterns start to appear:

If you often bust early with deep stacks, you may be playing too many big pots with one-pair hands or bluffing too much.

If you often bust with 15 to 25 big blinds, you may be calling shoves too loosely or opening and then calling off when re-raised.

If you often bust with under 10 big blinds, you may be waiting too long and shoving with too little fold equity.

If you bust a lot right after the bubble, you might be loosening up too much once you’ve secured a cash.

If you rarely bust by calling, but often by shoving, check whether your shoving ranges are too wide for your position.

Your bust-out log becomes a map pointing directly at your biggest leaks.

Part 3: Track Your Decisions by Stack Size

Results show outcomes. Decisions show skill. Tracking a few key decisions by stack depth helps you separate bad luck from bad play.

Short Stack Decision Log (Under 15 BB)

For each shove or fold decision you’re unsure about, write down:

• Your stack in big blinds
• Your position
• Your hand
• What you did (shove or fold)

After your session, compare your choices with a push-fold chart or training tool. Track your accuracy rate over time. Many players find they’re far more accurate at some stack sizes than others.

Medium Stack Decision Log (15 – 40 BB)

Focus on:

• 3-bet shoves you made or skipped
• Calls against all-in shoves
• Opens that you later folded to a re-raise

These spots are where many tournament players lose the most chips without noticing.

Deep Stack Decision Log (40+ BB)

Focus on:

• Big pots you lost with one-pair hands
• Bluffs that failed
• Hands where you were unsure after the flop

The goal isn’t to log every hand, just the ones that made you stop and think. Those are the decisions where improvement matters most.

Part 4: Track Performance by Starting Depth and Format

Different structures create different stack sizes, and you may perform better in some than others.

Group Your Results By

• Starting depth: Deep-structure events vs. regular vs. turbo
• Format: Freezeouts, re-entries, bounties, satellites
• Buy-in level: Each stake you regularly play
• Setting: Live vs. online

Why This Matters

You might discover that you have a strong ROI in deep-structured events but lose money in turbos, where stacks get short quickly. Or you might find your online results are much stronger than your live ones.

That’s powerful information. It tells you where to spend your bankroll, and where you need to study.

Part 5: Track Your Opponents’ Stack Habits

Tracking isn’t only about you. Keeping notes on opponents can be just as valuable, especially players you see regularly.

Useful notes to take:

• “Shoves very wide with under 15 BB from late position.”
• “Tightens up a lot when short-stacked near the bubble.”
• “Plays big pots loosely when they have a big stack.”
• “Rarely folds to 3-bets with a medium stack.”

Online, many sites let you add notes to player profiles, and tracking software can display statistics about opponents’ tendencies. Live, a simple note in your phone works fine.

Your Personal Stack Report Card

Put everything together into a simple monthly report card. Here’s a template you can copy:

Category	What to Measure	Your Result
Overall ROI	Net profit ÷ total buy-ins (with fees)	___ %
Most common bust-out stack	Stack range where you bust most often	___ BB
Most common bust-out stage	Early, middle, bubble, ITM, or FT	___
Short stack accuracy	Push-fold decisions matching a chart	___ %
Best format	Highest ROI format	___
Weakest format	Lowest ROI format	___
Total fees paid	All rake and registration fees	$ ___
One leak to fix next month	Based on the data above	___

Fill this in at the end of every month. Over time, you’ll see your leaks shrink and your strengths grow.

Tools That Make Tracking Easier

• Spreadsheets: Simple, free, and flexible. Perfect for results, ROI, and bust-out logs.
• Notes apps: Great for recording decisions and bust-outs in real time.
• Poker tracking software: For online players, these tools automatically record hands, results, and detailed statistics.
• Training tools and push-fold charts: Useful for checking your short stack decisions after a session.
• Tournament apps and live reporting: Handy for entries, prize pools, and payout information at major events.

Start simple. A spreadsheet and a notes app are enough to get real value.

Common Tracking Mistakes

Ignoring fees. Rake can turn a winning player into a losing one. Always track it.

Only tracking big results. Min-cashes and early busts matter just as much for your true ROI.

Tracking but never reviewing. Data is only useful if you study it.

Judging by small samples. Tournament results swing wildly. Look for patterns across many events, not just a few.

Focusing on luck. Your tracking should focus on decisions and patterns, not how often you lost with aces.

Final Thoughts

Tracking stack sizes isn’t just about knowing your chip count. It’s about turning every tournament and session into useful data: where you bust, how accurate your decisions are at each stack depth, which formats suit you best, and how much fees are really costing you.

With rake shifting across buy-in levels this year and record fields showing up at events like this week’s WSOP Circuit Main Event in Austin, understanding your real numbers has never mattered more. Start tracking today, review your data every month, and let the numbers guide you toward a stronger, more profitable game.
