I am stumped... And hopefully I can get some advice/answers... I go thru all of my errors when I am playing CV and these 3 popped up that have stumped me.. I played 471 hands and 19 came up as a loss due to deviation errors.. Still trying to memorize all 30 of my index plays.. Running a 97-98% correct play running rate.. So... just trying to figure out why these are errors??

Player / Dealer RC / TC error

10-8 / 4 1 / 0 STAND

10-8 / 3 5 / 3 STAND

9-8 / 10 2 / 1 STAND

My guess is I have an error in my customized index play I set-up....

Thoughts???
