Mhm. Forgot that the starting skill for an advance skill is higher than the old 1D6+modefier. 2 weeks might be more appropriate taking that into consideration.
My old houserules were that a trainer needed above 75% to teach, and that you couldn't train a skill higher than 75%, the rest had to be through experience (except for knowledge skills, which could be trained to 100%). That way you avoided rich adventurers taking years off to train their skill skyhigh.
