Archer question

[Blasphemous]

What exactly does it mean "You are an expert fletcher."?
I was level 17 and used fletchery set twice. Got 15 and 12 arrows.
Then I leveled up and used the same fletchery set with another stack of wooden sticks.
Result? Stacks of 9 and 11 arrows.
So how am I an expert fletcher when there is no difference?
Should I only make arrows from logs for it to have some effect?

(Blessed logs) seem to be the best for making ammunition - anecdotally, upon hitting level 18 in my current game, I made a stack of 80 blessed arrows of thunder from a single blessed log (easily obtained from the Animated Forest). Pretty nice! I've never, ever had anything like that come out of a stick, even a blessed one. Makes sense, though.

Also, this effect seems to reduce the amount of time needed to make ammunition.

I did some testing on this a couple of years ago and got following results:
- Being level 18+ archer halves the fletching time and if I remember correctly it also gives 1.5x number of missiles.
- Use logs! Those are way better than wooden sticks.
- B/U/C status of fletchery set did not seem to affect number of missiles.
- B/U/C status of log greatly affects number of missiles (something like 0.5x for cursed, 1x for normal, 2x for blessed logs).
- You get a lot more arrows than quarrels.
- Fletching time depends on how many missiles you manage to create (or would have created in case of failure). Arrows takes less time to fletch than quarrels.
