A formula that fits the five sets of results below for Partial Maps is:

(Silver Horseheads + 60) / 2, rounded up

And for Puzzling Maps:

Silver Horseheads / 60, rounded down

More data will help verify if these formulae are correct. If they are, Residualtoast would have got another Puzzling Map for one extra Silver Horsehead. Ouch!
