Critical CSS Style (max 2000)?

Dear,

I am using the trail version Google Pagespeed Tools plugin 3.9.
I have a problem with value of "Critical CSS Style (max 2000)", max only 2000 characters, while after I Created Critical Path CSS by https://jonassebastianohlsson.com/criticalpathcssgenerator/ then result is 23004 characters. so I could not use Optimization of CSS styles
with Critical CSS Style (max 2000) field.

Can you change unlimited value for Critical CSS Style (max 2000)???

no, no, no....
It's a very big CSS style size.
Plugin has to inline this critical CSS style into HTML page.
It's bad to have such big  critical CSS style.
Why?
Each request to server each time will have this critical CSS style ..... no. no.
You should use external CSS file.
Customer opens your store and he will not load this external CSS style again for second request.


Critical CSS style is very important feature, but you will not be able to do it automatically.
CSS specialist can create blocks and customer will see the main blocks before browser desn't load CSS style.

Don't use so big CSS style.
