When in doubt turn extrusion rate (flow ratio) to .95 as that will remove the majority of stringing caused by retraction being slightly off. PETG is one that creates wisps all the time though. In case ya need it when the wiper starts to bend and you’re tired of replacing it:
One very good test to further get accurate info is to print a 10mm hollow cube. This tells you about bridging, retraction, elephant foot, speed (corners), top layer surface quality, bottom layer adhesion quality (run your fingernail across the lines, if it goes deep nozzle is far from bed, if it’s fairly uniform and no drag on fingernail it’s good, if elephant foot present too close)… It also saves on filament and takes little time. You can also measure it and see how well the printer is calibrated or if nozzle is too close or belts too loose (10mmx10x10 vs 9.8x9.6x10.1 or such)
Your prints look pretty decent though
