Hello all,

I try to get the grades through the API in the xml file, but they are not available there. So my actual question would be how the grades are made by the data in the xml file? So that I could calculate them into a grade for my servers?

Looks at the score_* entries in the XML. Those are the scores for each of the checks and are translated to grades (90+ = A, 80-90 = B, etc).
Thanks! But how is the TTFB grade calculated? And how do you calculate the overall score (from what other scores)?
