And instead jagged frames duplicates used by sRestore or by IVTC.

not surprised that sRestore would prefer those lines, since it assumes it gets properly progressive input and it's about avoiding ghosting not combing.
Point is I doubt there are settings for either VIVTC (VFM+VDecimat) or TIVITC (TFM + TIVTC) using:

clip = havsfunc.QTGMC(Input=clip, Preset="Fast", TFF=True,FPSDivisor=2)
clip = core.tivtc.TDecimate(clip=clip)# new fps: 23.976

might be better.

"Input: Progressive + TFM" - There are plenty of normal (non-jagged) frames that may be normally used

Yeah, normally ivtc selects 4 out of 5 frames. you unless you find 4 good in 5 problematic frames ivtc has no chance.
as a side note: AnimeIVTC might work, but then again that would do tons of filteringe etc.
