Might be a tad bit late on this, but the animal caretaker can be boosted up amazingly fast if you embark on a tundra. The cold numbs dogs constantly, and they run over to your dwarf and hand him experience. Pretty sure he'll hit legendary in like a week if you have enough dogs (And you can embark with plenty, its not like you'll need to carry food or anything) Make sure your dwarves wear clothes though, otherwise they'll also start getting numb
Wow, another good idea!
Ok I might be about to lose power to a blizzard, but things to test next:
1) Animal caretaker on tundra (with a massive amount of dogs and cats)
2) Broker skill after enticing the caravans with huge piles of cooked cheesiness (specifically syrup roasts).
3) Three dwarves locked together socializing
4) Six dwarves locked together socializing
5) Three dwarves locked together wrestling
6) Six dwarves locked together wrestling
7) Perhaps throw a pump operator in. Definitely not the fastest, but a very common method which could use some information.
Try a quantum stockpile of food on a defined food stockpile - will the food rot? If not, lock a dwarf next to it with a kennel and try training Animal Training.
9) Job manager with legendary social skills vs Job Manager with same agility through pump operating
Huh! Lots to do. Breaking it down into forts of six subjects each:
1) 3 wrestlers 3 talkers
2) 6 wrestlers
3) 6 talkers
4) Tundra with massive mature agriculture industry. Animal Caretaker, Animal Training, Broker, Pump Operator, and Job Manager with legendary social skill. When the pump operator reaches the Job Manager's previous agility, make him Job Manager instead and compare. (The do-social-skills-help-level-job-manager test).
Thanks so much for the ideas!
