about caravan and gc leves: caravan 25+ gives max 50. Caravan 45+ gives max 150. GC 20+ gives min 40. GC 40+ gives min 90 max 130.

GC leves mostly says "protect a guy for 15 minutes) thats a 400 seals an hour.
Caravan gives 150, so its 600 seals an hour.

The best way to get seals are fishing, every 180 hours a new fish type pops up, and if youre lucky ... = win :P

I thought it would be people with more seals than me too though xD
