Documented first-party outcomes from players coached by Leonard Stakhovsky in Prague. This page states what was measured, how the result was recorded, and what the evidence cannot prove.
The outcomes below come from Leonard's coaching records, feedback, and before-and-after measurements. They are first-party evidence. They are not an independent study or an independent audit.
Results vary by player, starting level, training frequency, health, and match schedule. These cases do not promise the same result for another player.
