Used the retirement staking plan for a longtime, sounds similar maybe to whats being discussed here? Anyway it did work well, added discipline to my staking, its one thing finding a winner & another making some money out of it.

Lomaca in that respect any plan is better than none, but yep it does help to begin with if the selection method shows a profit at level stakes.

As for the Martingale, now there's one of the most destructive approaches to gambling i have come across, steer well clear.
