Here is the LRTimelapse preview for luminance (pink curve) with both non corrected and corrected EXIF shutter speed info.

LRTimelapse HolyGrail correction still have some problem when ETTR changes values every 1,2 or 3 pictures (the big bumps at the center) but if you look at the second part of the curve, it's more smooth now and the weird bumps with the 1/2 EV shutter values have now disapeared.

LRTimelapse will then do the job deflickering the all sequence (even with the non corrected version), but it's still better to start from right exif values (even if I don't know if the 1/181 and 1/203 are really the "real" exposition time but it's more accurate than 1/200 which I had before for both).
