Okay, I've let my training test run until Spring in the 2nd year. Here are the results.
This was their skills at the start:
Commander Recruit
Proficient Swordsdwarf None
Proficient Teacher
I equipped them only with training swords and let them have at it from Early Spring to Early Spring. Here's how they ended:
Commander Recruit
Expert Swordsdwarf Talented Swordsdwarf
Talented Fighter Talented Fighter
Novice Dodger Novice Dodger
Novice Student Novice Student
Novice Concentration Novice Concentration
Proficient Teacher Novice Teacher
Certainly not a bad result after only one year, although this had several things going in its favor. It was just one on one training, they were both equipped the same, and the commander was a good teacher to begin with. I can't help but feel that a lot of the commander's teaching potential was wasted, because the recruit became a competent swordsdwarf in the summer and after that they never did another sword demonstration. They would only do individual drills, sparring and the occasional Fighting demonstration when one got better than the other. Curiously, though, the commander trained the recruit from Skilled to Proficient in Fighting during the winter.
This leads to an interesting hypothesis: Are skill demonstrations capped at a certain level?
Right. I'm going to run another test now to see if I can learn more and milk Teacher skill for more of its worth. This time I'm going to go for two years in two different year long stages and I'm going to start with four dwarves training to start.
Dwarf 1 Dwarf 2
Proficient Swordsdwarf Proficient Shield User
Proficient Teacher Proficient Teacher
Dwarf 3 Dwarf 4
Proficient Armor User Proficient Dodger
Proficient Teacher Proficient Teacher
I'll have these four training in the same squad for the first year, then split them up into different squads and give them fresh recruits for another year. What I'm hoping will happen is they will teach each other their respective skills first, and then they will pass all their skills on to the new recruits.
Wish me luck.
