this question has to be asked every time so I guess it's my turn
We expect most players to get no more than 30k Mining experience per hour on average from fallen Stars.
we understand only 30k mining experience worth of stars may fall in an hour, but how much of that hour is actually mining the stars?
for example, if it takes 10 minutes, and a player mines granite at 120k experience per hour for the other 50 minutes (100k), they will have gained 30+100 = 130k experience in that hour
