"At the moment, I go virtual if I don't get a hit within a cycle, then re-enter after a virtual hit, using a mild progression. If miss 3 cycles, I'll still wait for another virtual hit before re-entering, but will now bet the very minimum until I get 3 hits that meet with the statistical expectations of the bet selection I am placing. After this, I'll return to my mild progression (using Lanky's divisor), but will be ready to repeat the above process if the hits don't come (or even quit for the day)."
