Early on, leveling up also means that you can put more rocks into the grinding machine with one grab, which is capped at (I think) level 24 at 10 rocks per grab.

There is no change in percentages. 1 rock will always be around 3.8 gralats per rock factoring in the probability of a rock "failing" to yield anything.

Definition of "profitable" is up to you.

I don't think high fishing level really means much in the end.

Also, Veteran Speedy Pizza has a huge confounding variable that affects the overall income, since more people crowding tables means a lower income generally speaking.
Alright, thanks for the info.
I'd read on these forums that Veteran Speedy Pizza has a setup that enables faster income, but it seems as though it's got a crowding issue. That's too bad, I almost have 3000 pizzas made.
I'm just not sure whether I'd like to spend so much time getting my mining level up.
