I'm trying the Google v5 API page speed insight but i don't find the SCORE inside the JSON result.
This is the api https://www.googleapis.com/pagespeedonline/v5/runPagespeed
In the v4 there is a ruleGroups.SPEED.score that contains an integer with the score.
Where i can find the score inside the v5?
I think it is the following: json.lighthouseResult.categories.performance.score
Returns a decimal with 1 as maximum. So you have to multiply with 100 to get the percentage. Works for me.. However I don't seem to get the same value every time. It fluctuates...
