I only say that because none of what I have read or heard about bare shaft tuning suggests turning the bow down before you start. Besides, once you are done bare shaft tuning, then turn the limb bolts up again you have changed the tune in some way. Either the tiller, nocking point, or dynamic spine. And you don't know if it was correct or not after doing it. If you leave the bases on the fletches the weight does not change enough to warrant it. And one full turn would be over compensating any way in my opinion, it would depend on the bow you have really. Like my bowtech is only 2 1/2 turns for a 10 lb weight range. You also change the FOC of you arrow as well if you take all the fletchings off, turning your bow down will not compensate for it.

And by the way I have tried it so I guess I can give my opinion on it then.

And I know some Olympic archers, one runs a local shop near me. To be honest they don't really spend all that much time tuning thier equipment because they know how to shoot. Most feel if you spend more than an hour or so on tuning you are just wasting your time. Form aiming and release are MUCH more important.

Of course if you are going to shoot animals with fixed blades I say spend as much time as you can until you get the results you are happy with.

And again remember, when using a release you can't go by what is listed in the tuning guides, you just have to experiment. The guides were meant for finger shooters. And with a release and a string loop things are even harder because the arrow flexes up and down not side to side. So spine issues may show up as high or low hits, not off to the side.
