Was trying to explore if any of the following Critical Rendering Path [https://developers.google.com/web/fundamentals/performance/critical-rendering-path/](https://developers.google.com/web/fundamentals/performance/critical-rendering-path/) influencing attributes show correlation to renderStart or speedIndex (for the time period 1-Aug-2017 to 1-Jun-2018).

SELECT  
ROUND(CORR(speedIndex, reqJS), 2) AS si2reqJSCorr,  
ROUND(CORR(speedIndex, reqCSS), 2) AS si2reqCSSCorr,  
ROUND(CORR(speedIndex, bytesJS), 2) AS si2bytesJSCorr,  
ROUND(CORR(speedIndex, bytesCSS), 2) AS si2bytesCSSCorr,  
ROUND(CORR(speedIndex, reqTotal), 2) AS si2reqTotalCorr,  
ROUND(CORR(speedIndex, bytesTotal), 2) AS si2bytesTotalCorr,  
ROUND(CORR(speedIndex, num\_scripts\_sync), 2) AS si2numScriptsSyncCorr,  
ROUND(CORR(speedIndex, numDomElements), 2) AS si2numDomElementsCorr,  
ROUND(CORR(speedIndex, avg\_dom\_depth), 2) AS si2AvgDomDepthCorr,  
ROUND(CORR(visualComplete, reqJS), 2) AS vc2reqJSCorr,  
ROUND(CORR(visualComplete, reqCSS), 2) AS vc2reqCSSCorr,  
ROUND(CORR(visualComplete, bytesJS), 2) AS vc2bytesJSCorr,  
ROUND(CORR(visualComplete, bytesCSS), 2) AS vc2bytesCSSCirr,  
ROUND(CORR(visualComplete, reqTotal), 2) AS vc2reqTotalCorr,  
ROUND(CORR(visualComplete, bytesTotal), 2) AS vc2bytesTotalCorr,  
ROUND(CORR(visualComplete, num\_scripts\_sync), 2) AS vc2numScriptsSyncCorr,  
ROUND(CORR(visualComplete, numDomElements), 2) AS vc2numDomElementsCorr,  
ROUND(CORR(visualComplete, avg\_dom\_depth), 2) AS vc2AvgDomDepthCorr,  
ROUND(CORR(renderStart, reqJS), 2) AS rs2reqJSCorr,  
ROUND(CORR(renderStart, reqCSS), 2) AS rs2reqCSSCorr,  
ROUND(CORR(renderStart, bytesJS), 2) AS rs2bytesJSCorr,  
ROUND(CORR(renderStart, bytesCSS), 2) AS rs2bytesCSS,  
ROUND(CORR(renderStart, reqTotal), 2) AS rs2reqTotalCorr,  
ROUND(CORR(renderStart, bytesTotal), 2) AS rs2bytesTotalCorr,  
ROUND(CORR(renderStart, num\_scripts\_sync), 2) AS rs2numScriptsSyncCorr,  
ROUND(CORR(renderStart, numDomElements), 2) AS rs2numDomElementsCorr,  
ROUND(CORR(renderStart, avg\_dom\_depth), 2) AS rs2AvgDomDepthCorr  
FROM  
`httparchive.summary_pages.*`  
WHERE  
\_TABLE\_SUFFIX \>= ‘2017\_08\_01’ AND  
ENDS\_WITH(\_TABLE\_SUFFIX, ‘desktop’)

reqJS, reqCSS, bytesJS, bytesCSS, num\_scripts\_sync, numDomElements, avg\_dom\_depth.

Was not able to observe significant correlation values. Is there some other attribute which can be used to get further insights on the impact of CRP w.r.t rendering performance?
