Printing time uncerteinty

I have a problem with printing time. There is very small difference in printing time after I change leyer height. I have prepared a printout with leyer heigt of 0.2 mm slicer shows it takes  7 h 58 min, if I change leyer height to 0.4 time is reduced only to 6 h 57 min. When i choose i3 MK3S printer with layer of 0.35 the time is 9 h 28 min, with layer of 0.2 time changes to 12 h 3 min.

I wonder why the time difference in Prusa XL is so small, I checked the speeds and nothing changes. I changed only the layer height, do you have any idea why it works like that?

Hi,

Thats because you have to Set the Maximum Filament flow. You can See the difference if you switch to Speed view in the slicer.

That's way too broad of a question for anyone to really answer without giving us two project files to compare for specifics.
