Those sound about "the same" for any kind of reasonable expectation...
I would guess you only want the correct order of magnitude... hours,
minutes, days, weeks, months, years... or maybe quick, fast, slow,
painful.
I do this soft of fuzzy estimation all the time when working on
Reproducible Builds in Debian; look at the past test history to get a
*rough* estimate of how long I might expect a build to take. This helps
me decide if I should start a build and get a $COFFEE, do some
$SWORDFIGHTING on the $OFFICECHAIRS, or sit and watch the progress bar
so I don't loose the mental state working on the problem becuase it will
be done $SOON.
Make it clear it's an estimate, or maybe even abstract away the time
units so that there is no expectation of any particular time.
I know there are people who would love to get a a value that was
consistently right but to be *useful* it only needs an estimate to be
mostly not completely wrong. At least to me. :)
