I was thinking a few days just so you're not shocking your body straight into less oxygen, I wasn't really thinking about how well you perform. I'd have thought in that it'd be better than jumping straight in with no acclimatisation, but you're probably more qualified to give advice than me as my experience is pretty limited!
