Year-Long Tracking of Every Cash Session: What Did I Discover?

A poker player recorded every cash session for a year buy-in, cash-out, stakes, duration and discovered surprising insights: the level he's best at is not the most profitable, win rate plummets after 4 hours, continuous tracking helps overcome results-oriented thinking. This provides data-driven improvement ideas for serious players.
A Reddit user shared insights from tracking each cash game session over the past year. He recorded buy-ins, cash-outs, stakes, session duration, and other data, and derived several key takeaways from it.
The stake you're best at isn't necessarily the most profitable
The data showed that the stakes he considered himself "good at" didn't yield the highest hourly win rate. High total profit might simply come from playing more hours, but hourly rate is a better measure of efficiency.
Win rate drops significantly after sessions of 4+ hours
By filtering by session length, he found that win rates declined sharply once sessions exceeded about 4 hours. He hadn't realized the impact of fatigue and tilt until the data revealed this pattern.
Tracking helps overcome results-oriented thinking
After consistently logging over 100 sessions, he gradually stopped obsessing over individual bad beats, viewing them as part of variance. The data helped him focus on long-term performance rather than short-term outcomes.
The challenge of tracking
Consistent logging was the biggest difficulty. To make it easier, he developed a device-side tracking tool that takes only 30 seconds to record. However, he emphasized that the key is learning from the data, not relying on any specific tool.
