How many hours per day/week do you model?

eh...it probably averages out to about an hour to an hour-and-half. Some days I have a lot of time between classes and little homework, so I can model for a couple or more hours that day, but the next might have more classes and activities so I maybe get an hour in spurts. Other days I have no time to model.

An hour a day would probably be the best overall answer, but I can get a lot done in that time.

It depends, because I go in spurts.  Right now, I haven't been at my bench for over 2 weeks, because in the summer, I'd rather be outside.  But when I do go on a jag, I'll spend 2 1/2 to 3 hours at a stretch at the bench.  Exception is when I use the time in the morning before I go to work, then it's only about half an hour.

When winter comes around, I'll have more sessions at the bench, because I'll be inside more, but the length of the sessions will be about the same.

Only 4-5 hours tops,its usually broken into very small sessions here and there,not usually more the 30 min at a time.
