How many dojos can one find this level of instruction? Where I train there is offered 12.5 hours of instruction per week plus some 5 hours kids/teen classes. Compared to many others it is quite a full schedule (one instructor for all). Previously I trained where there were ~19 hours per week of adult instruction. Besides Hombu and the Yoshinkan I have not heard of anyplace that offers anywhere near 40 hours per week of instruction. I'm not saying there aren't any but they are few and far between.
Generally, you have to go to more than one place, or train on your own. There's quite a lot you can do with solo training, and you don't have that dead time spent traveling to and from the dojo, hanging out before and after class, and so forth.
I don't get 6-8 hours a day, but I do get something going every day.
