the odds of you losing 100 times in a row out of 200 spins are exactly the same as you losing 2 times in a row out of 4 spins... exactly 50% (not counting 0 and 00 for the sake of argument).
The problem with this theory is the idea that somehow the fact that the spins happen "in a row" has a magical effect on the wheel.
Out of 10 spins:
win win win win win lose lose lose lose lose
or
win lose win lose win lose win lose win lose
the second one "feels" more likely but the odds are exactly the same.
