It's confusing nomenclature.
Any stroke play course may be played either as a) tournament, b) ranked or c) practice rounds. a) and b), that is those rounds which appear in the score history, count towards the "ranked rounds" number in the stats, but...
...only those rounds of a) or b) with an 18 hole par of 60 to 80 will count for the average, both in number count and score.
Vulgo, Par3s and Par5s are excluded from average calc but may count towards "ranked rounds".
