Ooh. I've had a pedant moment.

But it was mild - DH listening to football commentary - one man says "he's having a very average game. It's not like him". But if it's average, it probably is like he is most of the time. Or at least 50%.

Should I write in, do you think? And complain about the "very" while I'm at it.

If they do mean "average for all players", do they mean "all professional players" or "all Premiership players" or "all players of whatever standard including PortAndLemon". If they mean the last of those then I can see how it would be a bad thing.

did he mean "mediocre" ?

Instead of average, maybe a better word would be 'mediocre.'

To be a true mathematical pedant I feel compelled to point out there are of course three types of average, the mean, the mode and the median.
