   hi @kosiew !
   It is possibly a tooling issue. Yesterday, I ran `critcmp` on different 
`criterion` runs, and it showed results just like yours. My problem was that I 
forgot to use the `--save-baseline` argument for the `criterion` run.
   
   Could you share the commands you used to run the tests?
