Yes we run CI on MRs, but once merged into master CI is run again. It's only those metrics from CI on master (post merge) that are ultimately uploaded / used as a baseline.

Re the doubling of bytes-allocated on T9803, that's a good point. Due to the recent change in RSA keys, CI is recently failing to upload metrics (e.g. [1])! I'll fix that then see if I can track down where / if the metric has really regressed in master.
