What hotend / extruder combo are you using? You might just be seeing the the limits of that system. You can also increase the extrusion multiplier to get back to the correct extrusion width above the "drop off" flow rate. Althought now, it occurs to me that you would need a movement speed dependant extrusion multiplier for that to work well.
I'm using the Rapido UHF hotend in my tests with the clockwork 2 extruder. I'm definitely pushing the limits of the hotend(though not the heater cartridge), so I was testing to see if using the CHT could help increase those limits(unfortunately it didn't). that extrusion multiplier could work but I think the limited flow rate has more to do with the capabilities of the hotend, but I can definitely test it out to see!
I'd look at your extruder. For both to top out at the same flow rate it would make sense. From my own testing I did see gains using a volcano CHT in my setup. Also, with a Rapido UHF hotend and Sherpa Mini. It depends on your PLA as well. I've seen vast differences in max flow rate between them.
I'll look into that, I found that the CHT did give a less spotty(but still not perfect) flow at higher rates, it might be that will real world printing it's not a constant extrusion like the testing, which let's the plastic heat up more quickly. I definitely found that different filaments allow for higher flow rates too.
I found that if i pushed the nozzle temp much above the filament manufacturers recommended max temp it boiled the filament resulting in bubbles. At 275degC it seems you are way over what pla can handle....perhaps i misunderstood the values you provided for your tests.
I personally really like Prusa slicer since it has a good mix of being really to use but also allows you to get into more indepth settings if you want.

@OddSnail69 Definitely not worth the money, you're right it does seem to give a bit better flow then the knockoffs but only just barely.

I never even thought of that, that could definitionally be the reason behind the bubbles on the pla prints!
Which splicing software is good printing for 3d printer
I have ender3 v2 printer

@@gunneraberli how to
do .8Nozzle setting configuration
You might want to call in words and writing the flow rate in milimeters cube per second, definitely not milimeters per second cube.
Lol, you are completely right, no clue why I was putting mm/s^3🤦
