i read on the wizards site that insurance carries a 7.4% HA on a 6 deck shoe. How do you come to this conclusion? any help would be appreciated.

i tried the math at a $1 bet.

96 wins(2 to 1, totalling $192)
215 loses

-$23

23/311=0.07395

7.4% HA

is this correct?

There are 416 (52*8) cards in an 8-deck shoe. If the dealer has an A showing, there are 415 remaining. There are 128 face cards (4*4*8). You therefore have a 128/415 chance of winning 2x your bet and a 287/415 chance of losing 1x your bet. (128/415)*2 - 287/415 = -7.5%

Yes, that's the correct calculation. (96/311)*2 - 215/311 = 7.4%
