"3 numbers were inaccurate" (just an FYI for next time, no big deal)
"3 numbers were inaccurate" (and I am annoyed that I had to deal with the consequences, please ensure it doesn't happen again)
"3 numbers were inaccurate" (but I understand the pressure you were under and the volume of work you had, so I don't see it as an ongoing problem)

Sometimes the recipient of the message really does need the speaker's evaluation, not just the bare factual observations, to put the message in proper context. "My order took 4 days to arrive" is a lot less useful than "Thanks, my order only took 4 days to arrive" or "I had to wait a whole 4 days for my order to arrive".
