I'm curious, why 190deg and not 180deg ?

Stylistic choice? Didn't find any information why exactly 190deg, so assuming the author just liked it that way.

Made a quick demo showing the difference: https://output.jsbin.com/hujebimavu/1

I don't really see any difference between 180 and 190 though.

Thanks for the demo. I barely see a difference too.

Subjective choice, you can fine tune based on website.
