Why This Replaces Most of the Market
Because every product sold around these rounds makes a claim that a sheet like this can test, and none of them publishes the record that would settle it. Once you can run the test yourself, the question stops being who to believe and becomes what your own hundred rounds showed — which is a much easier question to answer and a much harder one to argue with.
It also removes the need to install anything. A notebook has no permission list, does not renew monthly, and does not have an incentive attached to what it tells you.
The Number Worth Watching
Turnover, not balance. Balance moves for reasons unconnected to your decisions and tells you very little about how a session went. Total staked only moves in one direction, it maps exactly onto expected cost, and it is the figure that responds to every choice you actually control.
How to turn that figure into a plan is on the stake and bankroll page, and every guide is listed on the home page.
