It's the numbers between the <experiencePoints></experiencePoints> tags in the save file, right? And I assume they're in the order you listed them, i.e. farming/fishing/foraging/mining/combat?
I tried changing the experience point values in my save file to be 1, in order to check which was which, but for some reason it didn't seem to change anything in the game. Could be because I didn't change the professions at all? IDK.
Here are the numbers from my main save, on summer 17 year 9, assuming the order farming/fishing/foraging/mining/combat:
Farming: 1,209,295 (!)
Fishing: 151,256
Foraging: 98,966
Mining: 180,223
Combat: 82,722
That farming number LOL. I've had a greenhouse full of ancient fruit plus ~400 spaces of miscellaneous crops for several years, but still.
Kinda amused that combat is so much lower than mining. The result of dodging enemies in skull caverns instead of fighting them, I guess? It's even lower than foraging, which I usually think of as the hardest skill for me to level, but I guess there was a period of time when I was constantly cutting trees for kegs.
EDIT: confirmed with
@BlaDe that the order is correct. Thanks Blade!
