Team 33 schedules 22 hours per week with our students during the build season. Our leadership and core students will typically put in considerably more than this, I would estimate average at about 36 hours/week or so. This is time where we are actually together at our build site. There is also a lot of individual time put on doing things like CAD, software, Website, documentation, etc outside of the actual on-site work.
This works for us, I have found more time in the shop can be counter-productive, and we must balance planning/designing with building/testing.
Too much of one will hinder the other, and we have a small leadership group so we need to share time between these two domains.
