I used the house advantage tool to calculate the house edge for six deck DAS, LS game (-.33) and eight deck DAS, LS (-.35). If a card counter were to play the eight deck game there will be a difference in advantage of -.02 for card counters. -.02 for a basic strategy player is not that much but for a card counter it could be a lot.

Is a difference in advantage of -.02 for card counters a lot?
