FAQ
What is grading based on?
The same simplified consensus ranges v1.0 as /charts: UTG 14.3%, HJ 19.8%, CO 26.7%, BTN 43.9%, SB 43.9%. Charts and grading share one data file — no inconsistency possible.
Is my progress uploaded?
No. All stats (attempts/accuracy/streaks) live only in your browser localStorage; the site has no account system.
Is this a real-time assistance tool?
No. It is a post-session study trainer for off-table practice; never use real-time assistance in live games.
