Extrusion Multiplier Results Highly Dependent on Nozzle Temperature #96

I am looking for feedback/thoughts about the way extrusion multiplier is suggested to be tuned on this site.

I was tuning extrusion multiplier (flow in Cura) for 3DXTech's CF-PA6 Gen 3. Printer is an enclosed linear-rail modded Ender 5 Plus with a Bondtech DDX V3, Slice Mosquito, and a 0.5mm Gamma Master Nozzle. Suggested printing temp for this material is 240-270 and I have always printed at the top of that range for strength. At 270, flow rate of 100 results in what looks like overextrusion on the top layer of the 30x30x3 test part. There is not a linear decrease in this appearance of overextrusion all the way down to 85% flow. I printed the 30x30x3 test part at 85% flow at 240 and there is clearly underextrusion. Printed the part at 85% flow and the sweet spot for under/overextrusion landed at 260 C. Is 85% a concerningly low flow rate? The part looks perfect at this flow and temp, but it seems like quite a large defecit of material.

Anyone have any thoughts on this?
