Is 100 PageSpeed ​​worth the effort and how to overcome render blocking css?

Question

Google

The Google PageSpeed ​​test gives me a result of 91. I just can’t overcome render blocking css, despite the fact that my CSS is not at all large, and visually I can’t recreate this situation when above-the-fold content is not rendered and I don’t understand why rating goes down.
The only way is to inline some of the styles in the head? How do you choose which styles to inline? This is what a hemorrhagic.
Is it worth the effort? Is 91 for mobile and 100 for desktop considered normal?

Answer 1

All these are formal parameters and estimates that are given not for blind following, but in order to assess the situation and understand what can be optimized.
If Google says there is render-blocking CSS, but you know it's not a problem, then so be it, don't worry too much about it. Always critically analyze the assessment and do not chase abstract parrots if it does not make practical sense.

Answer 2

There are more important ranking factors and more important things to spend time on than chasing nice numbers that maybe someday will give a micro boost to something.
