Does anybody get good results with the Slicer Standard settings for PET on MK3?

Hi,

I am usually using Simplify3D as slicer, but I got the same issue there as well. Today I upgraded to the new Firmware 3.4.0 and downloaed the DRIVERS & APPS 2.2.0. I left the MK3 profile for the Slicer as is and generated a Gcode file to print.
Default setting is infill with 200mm/s! Prusa is also avertising with this speed and so this seems to make sense.
Maybe I should mention that I recently upgraded the Extruder assembly to the new R3 parts and use the original PETG from Prusa. My Printer is set to sthealth mode, so the top speed is only 175mm/s.

This is how the print looks like:

The infill prited with full speed looks terrible and make the part unusably. The first Layer printed much slower is perfect.

And I made the same experience also with the other Slicers. But today after the firmware and software upgrade I wanted to make a "out of the box" with defaults test. Bringing down the speed and everything is ok.
You cannot print that fast with the Prusa MK3. So why do they advertise with those numbers and even distribute them in the profile settings?

Or is there anybody you can get any good refults with those settings?
