Topic: default extrusion width for .2 and .1 prints

I'm using a default extrusion width of .42mm for .3mm layer height. Are most of you keeping the width the same for smaller layer heights? I printed my first part at .2mm layer height today, and had to adjust the flow rate higher in RH, on the fly, while in the middle of my print. This makes me think the width should be smaller than .42mm. Any thoughts or experience with this out there? Thank you!

maybe this will help

this part :When you are printing at .3mm layers, a good Width over Thickness Ratio is 1.4, meaning the thread is 1.4x wider than its height.At .2mm thats .28

The rule of thumb is dont make the width smaller than the nozzle opening, so it would be a minimum of .35 regardless of layer height.
