It would be great to have personal rtp info to casino. I know that at least one casino has it and there you can even check your rtp for each individual slot. So it´t not impossible to do if you have know how and interest.
What do i do with that information? Absolutely nothing but it´s still interesting to see it and i would think that other Harry Slotters would agree
So please Unibet, do it and stand out of the crowd that don´t do it
