7. What is the long term? - Theoretically speaking, the long term
is forever. For video poker purposes, the long term is when you have
played a lot of hands (several million at a minimum) and actual
results are about the same as expected results. Tom Ski calculates
(with a 95% confidence factor) that the actual results for 10/7 DB,
played with perfect strategy, should be within 1.0% of expected
results after 1,085,465 hands, and within 0.1% after 108,546,482
hands.
I assume that by "within 1.0% of expected results" TomSki means 99.17%
to 101.17% return (100.17% +/-1%).
For 2sd (95%) at 1,085,465 hands I get 2sqrt(28/1,085,465)=.01 or 1%
which is the same result.
1% is a pretty big range in dollar terms, for 1,085,465 hands of 5
coin quarter play it represents $13,568
