Why It Survives Every Refutation
Because most of the evidence people have is genuine. A doubling ladder does recover small losses, most evenings, for weeks — and the person describing that is not exaggerating. The failure mode is rare by construction, which means the average player's direct experience of the system is positive right up until the session that is not.
It also externalises the failure neatly. When the ladder finally breaks, the story available is that the run was unusually bad or the table limit interfered, rather than that the tail was always part of the design.
The Honest Version of Recovery
There is not one. A loss already incurred does not change what the next round will do, and no staking pattern converts a negative expectation into a positive one. The only thing that changes is how the losses are distributed across evenings.
What a flat stake does instead is on the stake and bankroll page, and every guide is listed on the home page.
