The new rules are in line with the new focus on the community life, with all the duties and obligations. This is not anymore the full time adventuring we were accustomed to. Even if I prefer RQIII rules on the matter (if only because of the time to study being relative to the current level), I understand this. Where I have a problem is with the 'non tickable' skills, especially lores. With max 1D6-1 per season on 1 skill when you need to drive 2 or 3 skills to 90% means some runic ranks are impossible to reach in a lifetime.
The way I understand the new rules, he would gain 37.5% (on average) in addition to the other gains, because adventuring, learning and other are not full time. What we don't have is a rule for what you describe: somebody that learns full time, whatever the reason. The old RQIII rule could be used for that specific point (and no between adventure skill gain, no or half activity income, ...).
