You just had to ask didn't you? :o) Normally, I'd say at least 15-20 for me, but if things are busy less than 10. If I've got time (or procrastinate and make time or need the 'therapy' of it) I'm sure it's 30+. Part of it for me is still the learning factor. I may spend an hour tweaking a material or 2-3 hours modeling something where those may take others a fraction of that time. The good thing is I'm getting better so some things don't take me as long; the bad thing is that now that I've gotten those things down, I'm trying to learn even harder things. But hey, at least my mind's active! :o)
