this is a carry over from a previous question asked “alignment marks on MPF shafts”which mark is aligned with the target the target path?

Also, when a shaft is pured, I understand that this is supposed to be the most stable plane. Would this plane be the stiffest and would it be aligned with the target path or at the 12 o’clock position (per SST Pure).

With a shaft that is “flo’d”, the plane with the minimal amount of oscillation, would that be aligned with the target path or the 12 O’clock position. Also, would that be the plane with the highest frequency?
