Help me understand why dps can't be closer in damage output

Aaah, sorry, I totally missed that part. Yeah I should not have used median, I keep confusing the two. >.<

I don't see why you should not have used median. Median is a fine way to look at these things.
And when looking at the mean, that is still not "5.5%, or closer to 6%".

DRK 33237
MNK 33125
BLM 33077
VPR 33014
NIN 32917
SAM 32863
RPR 32593
PCT 31799
RDM 31246
SMN 31044
MCH 30619
BRD 30038
DNC 29813

Mean 415385/13 = 31952.69231
DNC deviation from the mean = 29813 / 31952.69 = 0.933

So DNC deviates -6.7% from than mean, or -8.5% from the median.
