【Gathering Data】Hunting Party XP gains by biome/trail size

Update: was able to see a medium in Swamp with only 497 relevant stats! Koios has 253/244 sniffer stats and 100% proficiency and found his first trail this morning.

Hi!

Proficiency plays a big role in exp gain, it's important to take it into account. (edit: checked switching up wolves roles for one hunt to have the same stats/levels on the exact same wolves, but with a proficiency that fell from 100 to 0 in one hunt: the exp gain were similar, proficiency doesn't matter; the erroneous conclusions were due to proficiency raising at the same time as levels and stats did)(edit2: In a hunting team of Lv1 wolves with some 30 some 100 in the relevant stats, they all gained roughly the same amount of exp; so the stats do not influence exp gain; but I realized a wolf I had that had first trained as a chaser then finisher got the same amount of exp at 60 finisher proficiency as another at 92 proficiency, because she has 60-ish proficiency as chaser; so the relevant stat is linked to all the proficiencies in all the different hunting roles)

Since I was curious to see how it worked, and what influenced hunting exp gain, I wrote down everything for a few days (something like a week ago), over all kind of trails in mountain and critter trails in swamp; I don't have the data on hand but I'll post it here within the next few days.

Unsuccessful small trail.

All wolves ended the hunt the same level they began with (however two can level up now), all full prof & synergy. Im in tundra right now. My stalker has never found a medium trail and currently has 250/243 = 493 necessary stats. 

Successful critter in the Desert.

Finished a hunt! Your hunting party, the Sunseekers, returned from their hunt. Grasspuddle captured the prey!

Dunestrider [Lvl 11] gained 125 EXP and +1 stalking proficiency point (new total: 100). +1 smarts (new total: 141)
Silverstripe [Lvl 9] gained 98 EXP and +1 chasing proficiency point (new total: 96).
Auburnripple [Lvl 3] gained 47 EXP and +1 chasing proficiency point (new total: 10). +1 agility (new total: 95)
Milkweed [Lvl 3] gained 46 EXP and +1 chasing proficiency point (new total: 10).
Grasspuddle [Lvl 11] gained 112 EXP and +1 finishing proficiency point (new total: 100).

So my stalker finally found a medium trail in the tundra. Failed it of course because of 4% possibility but here’s the stats:

Stalker has 499 combined sniffer stats. All are same levels.

Top and bottom wolf are lv 20, middle 3 are lv 13. All full prof and synergy.

So!

Stats time.

First: raw stats: each entry is in the format: Stalker exp-proficiency-level Chaser1 exp-prof-lvl chaser2 exp-prof-lvl chaser3 exp-prof-lvl Finisher exp-prof-lvl or Stalker exp chaser1 exp chaser2 exp chaser3 exp finisher exp.
Since it's in chronological order for each team, you can interpolate the proficiency where it's missing by adding one each time, and in the few days I wrote this down no wolf gained two levels, so they're max one level higher than they were at the start (I tried to always write when they leveled up but I may have missed a couple).

Interpreting that data in a more readable format:

Does proficiency matter?

Yes. It seems like all hunting proficiencies, not just that of the current role, matter. More testing required, I'll update later with the data.

Which trails should I choose?

If exp gain is more important than food, always choose the harder trail even if it's 0%: While getting the prey is better than not, better a bigger prey that you fail than a smaller one that you get. See data:

For a lvl 7-8 chaser at 100 proficiency in the mountains biome:

critter failed: 28
critter gotten: 33, 31, 32, 33, 35
small failed: 43, 41, 41, 45
small gotten: 47, 47, 57
medium failed: 55, 64
large failed: 73, 67, 74, 76, 82
large gotten: 78, 97, 87

Does lvl matter for exp gain?

Yes, higher levels give more exp (to check further). See data:

for a lvl 8-9 finisher at 50-60 proficiency:

critter gotten: 36, 34
small failed: 44
medium failed: 64
large failed: 73, 76, 77
large gotten: 90

for a lvl 5-6 finisher at 52-65 proficiency:

critter failed: 26
critter gotten: 28, 30, 30, 29
small failed: 34, 37, 40
small gotten: 46, 46, 56
medium failed 46
large failed: 56, 64
large gotten: 75, 99

Do stats matter?

No. See the following log; wolves (they're level 1, it's their first job) are named Role + stats in relevant roles at lvl 1 (might vary by 1 or 2 if there are several different relevant stats) + total stats

Stalker32-161 gained 28 EXP and +1 stalking proficiency point (new total: 2). +1 smarts (new total: 33)
Chaser34-179 gained 27 EXP and +1 chasing proficiency point (new total: 3).
Chaser33-162 gained 27 EXP and +1 chasing proficiency point (new total: 3).
Chaser101-450 gained 27 EXP and +1 chasing proficiency point (new total: 2).
Finisher101-419 gained 28 EXP and +1 finishing proficiency point (new total: 3).

Do biomes matter?

Yes: for a failed critter hunt with 100 proficiency in the swamp (so with team 2), I consistently get between 100 and 126 exp (I don't have data for any other kind of hunt in the swamp XD). So if you need exp, go to the hardest biome you can (and be prepared to get food some other way).

Notes: 

My stalker failed a small hunt at 39 proficiency and got 37 exp, and the next hunt (also small and failed), at 40 proficiency, they got 34 exp: so the variations are not due only to wolves gaining in proficiency over time, there is a randomizer.

It seems like each role gets the same amount of exp, all other factors being equal, but I have insufficient data to be sure.

I didn't take seasons into account, but I got this data (except for the proficiency test) on 2021-06-01 and 2021-06-02, so all hunts could have been on the same season.
