Default 05 STi compression test numbers, should I bother with a leakdown?

Hey guys,
So ive been having a strange issue where my 05 sti doesnt always engine brake while decellerating. IAG said that among other possibilities, it could be a low compression problem, which prompted me to get a comp. tester and find out. Here were my numbers:
(cold engine, about 500ft elevation, all plugs removed, WOT, ingition fuse pulled)
Im very happy with the consistency, however these numbers seem a bit on the low side. I know with the engine warmed up the #'s might be higher, but my question is should I be concerned? And do you think its worth performing a leakdown test?
