suited BJ 75-1

I have been putting in a great deal of play on a pretty strong double deck game with a suited BJ sidebet which pays 75-1 recently and doing pretty well. It looks to me that from CVdata that you begin to have an edge at the side count bet pretty early on, like a hi-lo TC of +2 and it goes up pretty rapidly at about 4-5% per true count from there. Am I figuring this right?

Looks good to me. The player ev is -.092 off the top, and goes to +.002 if you remove 5 non ace face or ten cards. and +.023 if you remove 6 non ace face or 10 cards. I made a google docs spread sheet.
