I'm wondering is there a capp for Output.
Right now my Output is 111 (BNT41), and I'm able to do 7 attempts on Grade 5 spot.

When i was skilling my Carpenter and went to farm some Grade 1 logs I also were able to do 7 attempts for each spot.

So I guess stacking more Output is pointless.

What I've also noticed, is while i was leveling and my Output was the same for 3-4 levels, the number of attempts raised. So it must be some other factor which determines it.
