Prusa Slicer 2.4.2 gcode time estimate much longer than 2.2.0+ (and 2.2.0 seems accurate)

Hi all,

I have PS 2.4.2 installed on one machine, and PS 2.2.0+ installed on another.   I load the same exact .3mf file into each version and generate gcode without changing any options.  Both are in normal mode (not stealth.) The time estimates for each are:
2.2.0:  5h 56m
2.4.2:  8h 19m

I printed the 2.2.0 version gcode and the estimate was pretty close - it actually completed ~9m faster than estimated.  Anyone know off-hand why version 2.4.2 gives an estimate that is almost 2.5 hours slower?

I did notice on quick glance that the the speed and acceleration values are the same and that the 2.4.2 version is 116,253 lines longer than the 2.2.0 version, but I haven't done a detailed parse of the two different gcode files produced. Thought I'd ask if anyone already knows what is driving the time estimate and gcode gen differences.

Thanks much!

PS 2.4.2 (perhaps earlier vers as well) has a feature to compare profiles. Its on Windows/Compare profiles. All may be revealed.
