The "Happy hour theory": Some hours or periods have bigger success chance than others.
Example: At some periods, triple Chance might be 5% and other 15% with an average 10%.
How to test this? My suggestion look at waiting times. Number of spins from between one triple chance to the next.
If chance of triple "Chance" is, constant waiting times will follow an exponential distribution.
If happy hour theory is correct we could get more very short and very long waiting time.

I also look at how often did SR come in same spot 2 time i a row:
4 out of 24 times or just 1:6. Not much better than the 1:6 chance you get by picking at random.
