It can still matter... Why would you bother splitting hairs on how "much" it can fluctuate?? It can be a difference of someone having theirs at 6 and someone else needing to set it at 6.5 for the same result. What other variables do you think are responsible?
I'm not splitting hairs, I build coils myself, that's why I know.
Variables include: strain, humidity of strain, grind, pack, draw strength...
