Trade skill skillups (Fletching)

[kschuder02]

Has anyone else noticed an incredibly bad skill up rate with trade skills (I have noticed it with other skills as well, but this thread is about Fletching in particular)?

A list of my stats as I am not sure which one would influence Fletching skill ups:
STR 90
AGI 85
DEX 85
WIS 80
INT 75

I did 120 combines and only got 7 skill ups. That is ONLY 1 out of ever 17, or so, combines. I started with 35 skill and ended with 42. I was combining something that was trivial at 46, so it wasn't very far away from my current skill. Not sure if 7 out of 120 is normal, but, to me, that seems ridiculously low.
