Research direction
Reproduce the mismatch using sitespeedio/sitespeed.io:17.0.0-alpha.2-plus1 with both lighthouse and gpsi enabled, comparing the first and subsequent runs. Inspect the plugin’s Lighthouse metric collection and Graphite/dashboard output against lighthouse.pageSummary.json for FCP, LCP, TBT, and CLS. Done means repeated runs consistently report values matching the JSON file.

Description
Hi Peter, sorry to bother you.
I have been testing your alpha release you made to store lighthouse web vitals to graphite and display value on dashboard sitespeedio/sitespeed.io:17.0.0-alpha.2-plus1 . I noticed weirdness with values, I am not sure if i am correct but i also understand that its not a stable release yet. I am able to display data in dashboard but those values do not match with lighthouse.pageSummary.json report file. FCP LCP TBT . maybe i am looking at it from a wrong view but i am correct to say those values should match ?
CLS seems to always be correct but the rest do not match.
I have both lighthouse and gpsi enabled.
it seems like on the 1st run it match with report file but any subsequent runs just looks off.
