It may be just as useful to write one special .exp test cases that
extract those numbers for the limiting scenarios (say, a nearly blank
probe script, and a slow one with syscalls.*, and maybe one
intermediate "typical" one). The .exp script could pass the times
straight into the test summary. No need for email or spreadsheets.
