If my pc can handle it I think I might start using it. But ignorance is sometimes bliss, if I find my rtp is 60% on a slot am I more likely to then chase on the basis of the law of large numbers or an overdue rtp correction, or if it's the other way 120% stop playing a game when it could still be a good game to play...
Everything is tracking us online in one way or another but you can never be too careful I guess.
You might already understand this, but just in case, the law of large numbers only works in percentages.
For example, maybe you flip a coin 100 times and get 40 heads, for 40%. Say you flip it another 900 times and end up with a total, including the first 100 flips, of 450 heads. The percentage is now better at 45%, but you're another 40 flips below average. (Though you could just as easily have ended up with 530 heads after the first 100).
So while the percentage will tend towards the average over the long run, it has absolutely no bearing on whether or not continuing to play the slot will improve or worsen your results. It's not really that the RTP "corrects," rather, there's simply more results to drown them out - and in some cases, that drowning out would involve substantially more losses or winnings (technically it's difference from the average, which favors the casino at 96% or whatever for that particular game, so it takes more and more difficult to achieve amounts of luck to stay above 100% in the long run - since that's 4% over the average - but your losses are basically unlimited.)
In other words, there's no need to avoid playing a game you've done well on or to keep trying at a game that's gone badly. Your odds of winning or losing are the exact same as when you started, regardless of previous results. So best to just play whatever would make you happy, whatever you enjoy, whatever has the variance or win potential you're looking for, etc.
