Hi,

thanks for this awesome profiler!
I cannot found any info on the doc re how to interpret samples count while using -e cpu and -e itimer. I wouldn't like it to became a blog about how sampling profilers (should) work, but I admit that writing 2 lines of doc there could help to understand the difference in samples count a user can expect depending on the context.
We can start a discussion here and I can send a PR to add it, if is welcome 👍

thanks,
Franz
