It is sometimes confusing.
You can see it the previously posted Photo I am printing in the Yellow.
It clearly shows that printing over 8.0mm^3 Per second could cause filament slippage.
With my Settings that Max speed percentage is 71 being 8.0mm^3 Per second, an 72 being 8.1mm^3 Per second.
I have successfully printed many models at over 100% " (11.2mm^3 Per second) " using PLA though have yet to venture this on ABS.

I prefer to stay closer the upper limits I determined make the best Models. 8.0 - 9.6mm^3 Per second.
