I am not sure I see any such "well versed and articulate" person coming to the thread to provide this information, so care to give it a shot? I'm sure you'll do just fine. If I am truly wrong, it would be appreciated. Alternatively, if someone has provided this information elsewhere, you could provide a link.
Without knowing exactly how a jackpot works, it's always going to be theoretically possible that the contributions will add up in some incredibly bizarre and convoluted matter, but generally I don't think that's likely. I've tested with two different methods on both a low total jackpot and 2 different high total jackpots, with two different methods, getting a number well under 1% each time. The only other info I've seen is "he said, she said, I once heard from a reliable source," etc., that isn't really very useful.
As for the "yay I disproved them": who is the "them," we are referring to? I already provided a possibility of how the 1.5% could be true, I didn't say RTG is lying. It may just be that no reputable casinos use the setting which gives 1.5%. RTG slots paybacks are generally known to be configurable to a few different payback settings. (On that note, it would be nice to know if any of the accredited RTG casinos do use the high setting, because I like the games aside from the fairly high house edge.)
It could also be that the chance of hitting the jackpot+jackpot contribution varies by the slot played, perhaps I'll test that more another day.
Yes, and when the jackpot is hit, the corresponding jackpot is reset for all of these slots. If you are implying that the contribution appears smaller because it is actually split up between separate jackpots for each slot, that doesn't really make sense because they all function as one combined, single jackpot.
Additionally, the possibility that others are playing at the same time, screwing up my testing just means that my estimates are the MAXIMUM possible value, other players adding their own wagers would mean the value is even lower.
