Analysis of compression check data

Data from my recent compression check on the 1275.
What does this tell me?  Looks like #3 is low compared to the other cyl but
still pretty good numbers.
You engine gurus, please give your .02.

Hot, all plugs out, throttle(s) wedged open
cyl     dry             5cc oil %Diff
1       182             187             2.6%
2       167             202             17.3%
3       140             174             19.5%
4       182             213             14.5%
