Steps:
I crafted a dagger soup for the first time and received this message in log
[6:17 p.m.]You synthesize a bowl of dagger soup.
[6:17 p.m.]You gain 6 (+20%) experience points.
[6:17 p.m.]You gain 5 experience points.

I tried it again and got this as an result
[6:18 p.m.]You synthesize a bowl of dagger soup.
[6:18 p.m.]You gain 10 (+100%) experience points.

It seems very odd that a level 50 craft gives almost no exp what so ever.
