I hope this doesn't get moved to the Disadvantage Forum

Has anyone ever simmed the idea of playing a Martingale progression (up to the table max) only when the count indicates an advantage. For instance, my usual game is 8D, S17, LS, DAS 6.5/8 pen $10 minimum and $500 max. My usual spread is $10 to $150 with Wong in at +1 and Wong out < 0. I bet $10 at TC0, $25 TC1, $50 TC2, $100 TC3 and $150 TC4 (HiLo with indices). I find that with an 8 deck shoe I'm very rarely seeing high true counts. What if I double my bet after any loss when the TC is +1 or greater and go back to $25 after any win? If TC is 0, I bet the table minimum and I leave when TC goes negative. This would seem to provide great cover. I suspect it would add considerably to variance and ROR but I didn't know so I thought I'd ask.
