Reading replies with interest. So far, with DS8, it's worked fine to say that practising daily (unless there's a genuine reason why it's impossible some day) is a condition of having lessons. You don't feel like practising today? Ah, so you've decided to give up this instrument. No? Off you go to practise then. (I present this as partly a value for money of lessons issue, but more a respect for teacher issue.)
I do think the "daily" rule is probably a lot easier to insist on than something less than daily but more than not at all!
