    Update from David:

    Added an Overall RTP % field, in case the player knows this from a PAR sheet or some other source. It works like this:
    • Base Return % = expected payback ignoring the jackpots (what most MHB calculators use).
    • Overall RTP % = overall expected payback including jackpots (what a casino means when they say “our slots return 90%”).
    Type in either, the other fills itself in. Whichever you typed last stays fixed, and the other recalculates when you change the seed, must-hit-by, rise, distribution, or meter count.
    Example: Pin Base Return and switching to Right-weighted lowers Overall. Pin Overall and the same switch raises Base Return instead.

    It’s going to be rare when the PAR sheet is known, but this can only help in rare cases where this info is available. As he mentioned, if you don’t know the overall RTP, just put in whatever base return % you feel comfortable with; 80% is the default conservative figure. That will then auto-fill the overall RTP %.
