Win,lose, push question

The usual win, lose, push stats looks something like this (given for 1 deck): 43.8 win, 47.94 lose, 8.26 push. If one was never to double (play out you usual double as a hard hand and play out the splits as if the 'no double after split rule applied', how would the percentages be changed? I expect more wins and pushes and less loses, but how much more? If you could provide stats for 6 decks I would greatly appreciate.Regards, Picasso.
