betting scheme

Posted this below, but thought I'd start a new thread up top.

I think I'm going to try the following betting schedule on a 15 dollar table with a 10K BR. Any thoughts are appreciated.

On a 15 dollar table.

<3 15
+3 and +4 25 (1 and 1.5 % adv.)
+5 and +6 50 (2 and 2.5% adv.)
+7 and +8 75 (3 and 3.5% adv.)
+9 and 10 100 (4 and 4.5% adv.)

Betting 15 on counts +3 and lower should reduce the RoR right? Is this a legit betting scheme. I realize that counts justifying 100 and even 75 dollar bets using this scheme are relatively rare, especially in a 6 deck game. Will they occur often enough to gain an advantage. Any thoughts are appreciated.
