After having Dan suddenly overtake Max in xp the last couple of weeks I took the time to go through all sessions since Week 11 (Berg's first appearance) and find out why that is.
Below follows my findings and some comments:
Before research: Berg 6290/6500 XP
After research: Berg 6502/6500 xp
Week 11: 0xp - 95xp
Week 12: 95xp - 158xp
Week 13: 158xp - 442xp
Week 14: 442xp - 626xp
Week 15: 626xp
Week 16 (Liveshow): 626xp - 1095xp
Week 17: 1095xp - 1675xp
Week 18: Volnach
Week 19: Volnach
Week 20: Berg: 1675xp - 1842xp(+40 Giant Spider/5 Characters); Volnach: 1834xp (+40)
Week 21: Berg: 1842xp - 2125(+40); Volnach: 1834xp (+40) (Death)
Week 22: Berg: 2125xp - 3042xp (+40); Azriel: 2749xp (+40)
Week 23: Berg: 3042xp (+40); Azriel: 2749xp (+40)
Week 24: Berg: 3042xp (+40); Azriel: 2749xp (+40)
Week 25: Berg: 3042xp - 3326xp (+40); Azriel: 2749xp - 3033xp (+40)
Week 26: Berg: 3326xp -3829xp (+40) Azriel: 3033xp - 3536xp (+40)
Week 27: Berg: 3829xp - + 700 + 400(Missed "Jellies+Fungus")+ 235 - 5164xp (+40);
Azriel: 3536xp - +700+400+235 - 4871xp
Week 28: Berg: 5164xp - 5927; Azriel: 4871xp - 5634xp
Week 29: Berg: 5927xp + 763(Incorrect duplicate) 575(Correct Wyvern) - 6502 (lvl 5!);
Azriel: 5634 - + 763(Incorrect) 575xp - 6209xp
Berg is missing 400xp from week 27. Berg & Azriel are missing 40xp from a giant spider week 20.
At the beginning of Week 29 @AdamKoebel mistakenly gave them the xp from the Kobold fight again (763xp) when in actuality they hadn't gotten the xp for the wyvern fight (575xp).
Bergs total xp at the beginning of week 29(Note!) should therefore be 6502 (lvl 5), Azriel's should be 6209 and Black Gale & Nak'ana Ino should have their xp reduced by 188.
It was discussed that Max would be allowed to transfer some amount of xp from one of his characters to the other when he played both Berg & Volnach when that adventure was done and one character had to leave. It was not touched on again when Volnach died, so I have included Volnach's xp in case that's a thing that is still on the table. The amount of xp over his starting xp (900) is 934.
None of the main-cast got any quest-finished xp for the previous quest (Drug-mining operation, dinosaurs, drugs, weird floating crystal, you know the one) so players might want to inquire about that as well.
It might also be worth noting that the players have not yet recieved xp for the big fight at the end of week 29. Just to make sure that's been mentioned. Chuckles MVP.
Bergs total xp at the beginning of week 29(Note!) should be 6502, Azriel's should be 6209 and Black Gale & Nak'ana Ino should have their xp reduced by 188.
