I am under the assumption that you know that if you posted the correct figures i would be proven right, which is why you are deliberately posting incorrect data
Get one thing straight
0.675 is indisputable fact, it is not 0.70 like you said earlier, it is not even 0.68, it is 0.675, the hand is made, you know your final total, and you know your odds of getting beat.
So it is you who is in disagreement with the mathematicians, not me
Sorry Michael. I responded to the bait. 
The numbers vary according to rules and decks as follows:
Multideck, Stand on Soft 17 — ~0.70
Multideck, Hit on Soft 17 — ~0.675 (I round to 0.68… the precise number varies with number of decks)
If you doubt these numbers, look them up at Wizard of Odds or some other reputable site, using both sets of rules. The difference in values occurs because there are different chances of the dealer drawing 21 and drawing 19 or less with the two dealer strategies — hit on soft 17 and stand on soft 17.
Why do you care so much about the precise value down to the nearest thousandth? We haven’t used that level or precision elsewhere in the thread. Regardless of which of these numbers we use, the higher EV move is standing, not splitting. It’s not even close.
