yes this is true but i was talking about when the count is positive.
I probably wasn't very clear.
I think most people only spread to multiple hands when a max bet is called for.
Anyway that's what I assumed.
So, given that, the fundamental reason is that you get more money on the table playing only 1 hand when heads up compared to 2 hands.
I also assumed that when you do spread to multiple hands you don't double your max bet but bet an amount that keeps your original ROR the same - so maybe 50% more total bet or so over 2 hands.
In any given game TC's will occur at a certain frequency whether you are max betting, playing all or wonging in whatever way or not.
So, I suppose you can always make the assumptions of x-cards per hand, hands per round and therefore cards per round given how many players and determine which option gets the most money on the table given your 1-hand bet and proper amounts bet when spreading to keep ROR the same.
Basically, I believe it's just as you say, only play one hand when heads up. You will get more money on the table that way. Unless, also like you say, you know it's the last round of a positive shoe.
