WPT vs. Navigation API
Hi Pat,

First of all, let me say thank you for this great piece of software. We are using it as private instance for nearly a year and it really helps working on performance-issues.

My question:
Besides WPT we use RealUserMonitoring to get loading-times. For that, we measure the "loadeventStart" of the W3C navigation timing API.
If I compare these values with the "document complete" values from WPT, the RUM-values always are clearly worse: around 1-2 seconds which is nearly 50%. We compare same pages and same browsers over a longer period (2 weeks).
TTFB values do not differ significantly.
Before investigating further, it would be helpful to know, if the W3C "load event star" event is the same as the WPT "Document complete".

Should the events used by us be the same (from a technical point of view)? Or did we miss something? Is it actually possible to compare WPT and navigationtiming-API timings in a meaningfull manner?

I'm happy to hear from you soon,
