Haha sure, ive trained like erm 20-25x legit 99 combat stats in there. If youre telling this about the exp rates then it all depends on the gear, inv and ofcourse lazyness about using power surge with gmaul.
Ive done alot training from 75+ str too 85+ so pretty much if going pure gear gmaul power surge thats ~37k hour but still no way on getting 76-85 withing 72 hours also having some rest.
Claiming 72 hours straight up training is bs, i more likely call it boting.
