What factors determine skill improvement? I know it has something to do with age, dedication, potential, and team. I also know training speeds up in the month prior to a fight.
Does the existence of other fighters (training partners) impact it? Or any events, rival companies, or the fighter's location, or anything else?
Also, the up and down arrows in the skills window - do they reflect the training that day, that month, or over what period of time?
