HELP for counting the house edge if BJ could split it freely

There's some casinos exist the rules as you could split your hand freely with any pair, player splits for two reasons, one is increasing value like 8,8 vs dealer 2, and one is decreasing lose value like 8,8 vs 9, I'm just wondering is that possibly over the house edge?

According these rules
Six decks
Stand S17
split any pairs(include aces) 4 times(no drawing by splitting aces)
Double any initial hands
double after split allowed
early surrender against 10
player loses original bet when dealer got a BJ

According to my counting by using Excel of infinite decks, the player advantage would be 1/2755, but I'm not pretty sure if my counting correct, so I'm asking is there anybody could help me solve the question, thanks a lot......

Check out the blackjack calculator on the sister site.

this calculator couldn't help because it can't count the rules when you could split your hand freely, it's different from the regular BJ rules

Free splits adds about 0.17% to 0.20% to the player side, depending on the rules.
