My understanding is that if you pured for a right handed golfer then the pure mark goes in the club at the 12 o’clock position. So my question is would it make any difference if the puring mark went in the 6 o’clock position? Asking because my fitter did this on my sim driver. He says it doesn’t matter, and if I rotate the shaft 180 degrees it changes the lie angle from 54 to 60.
Puring does find the principle plane of oscillation (PPOP) and identifies the orientation at which the shaft will perform as if it were perfectly straight and perfectly round. We know that no shaft is perfectly straight and perfectly round, so the process helps eliminate an inconsistency that is inherent in golf shafts. SST PURE recommends the Pure mark go in the 12 o’clock position, placing the stiffest side of the shaft to the target. If yuo place the mark at 6 o’clock, it simply places the more flexible side to the target. It is still in it’s most stable plane. What difference can in make, or can player even tell the difference? It would depend on the player and how finite you want to get in analyzing ball flight data. In theory, if you want a slightly softer feel and want to enhance trajectory, go weak side towards the target. If you want a firmer feel and want to control trajectory and maximize distance, go with the strong side towards the target. Again, I doubt most would notice a difference and the important thing is that in either position dispersion should be improved.
As far as changing the lie by 6 degrees if you rotate it 180 degrees, I have no idea where the fitter got that information. I have no data or information that would support that. Rotating the shaft 180 should not effect the amount of droop (in my opinion, and experience), and even if it did for some players it would not be by 6 degrees.

FYI – The Taylormade Shaft Adjustment Sleeve Tuning Manual does say that the Lie Angle will be adjusted by 4 degrees from 60° in the Upright Position to 56° in the Standard Sleeve Position. Not 6 degrees. Has nothing to do with shaft droop, just measuring the angles. Would be interesting to see if all companies adjustment sleeves really do create the stated changes to Loft, Lie and Face Angle.
Here is a link to the Taylormade Tuning Manual: https://www.taylormadegolf.com/on/demandware.static/-/Sites-TMaG-Library/en_US/v1606840375297/manuals/2020_tuning_manual.pdf
Interesting that they claim that the RPM (Backspin Revolutions Per Minute) can increase or decrease due to the change in loft. I’m sure it is golfer specific, but in theory, adjusting to less loft should decrease the spin… while adding loft will generally increase the spin rate.
IMO I’ve only used Pured Shafts in the 12-O’Clock position, but may try out what Britt said about creating a softer feel and enhancing trajectory with installation in the 6-O’Clock position.

Puring finds the most stable plane, regardless of the spine and flo oscillations.
Just because the POP is at a certain point, it doesn’t mean it extends through the shaft 180 degrees.
The puring folks SST Pure, specify puring for right or left handed golfers.
