Question about power ratings

[seraphim-12.livejournal.com]

Hey everyone! I was just wondering, if it was ever mentioned, what was Neets power level when she 1st became a wizard? I was just reading HW and was curious to know if it was ever stated. I know there was something at the end of DW, but me have no books, so can't check!

One more question . . . hoe exactly do you read the rating? there's a + sign which i assume is the power they have and then the / and - sign . . . I think? So is that the power that's been used or . . .what? thankees for any ideas !

That's plus/minus notation, used for indicating tolerance or accuracy. X +/- Y means that the value is somewhere between X-Y and X+Y.

If you have {1stnumber}+/-{2ndnumber}, that generally denotes either a statistical range around a central point, or a measurement uncertainty. For instance, 5+/-2 would indicate that you should generally expect to see values between 3 and 7, but most commonly in the middle. OR, it could theoretically mean that it looks like 5, but that could be off by about two.

If it's statistical, I don't know offhand whether wizardly power ratings are listed with a range of one standard deviation, a 95% confidence interval, or what. (If it's one standard deviation, you'd figure they're within the given range around 2/3 of the time; if it's a 95% confidence interval, it'd be more like 95% of the time...) It might not even be Gaussian....
