Paper resistance is imbalanced during calibration

[cliffyk]

i just reread that other thread--don't know why I missed it previously, however the lift speeds you indicated;

Bottom lift speed: 90 mm/min
Lifting speed: 100 mm/min

are VERY aggressive. The higher the inter-layer lift speed the higher the force required to tear the last printed layer from the FEP--which can tear the last printed layer from the platen instead.

Try reducing them to 60/80 (bottom/normal) and see if it helps consistency.
