That's a very good question. For very stable accelerator conditions, you might not don't really need to update but every hour or two. ButHowever, for example with that AMO experiment it drifted with some special configurations it can drift measurably over as short as twenty minutes as the beam was a trick setup and some feedbacks needed disabling. That's typically for cases where we have to leave feedbacks open (two bucket and some twin bunch configurations).

There's not really a hard, fast rule here. When necessary or when time allows has been Definitely when necessary due to known changes in beam conditions and otherwise as often as time allows is the practical answer so far.
