Maybe... I'd buy all lq ones you have tho

This price range is indeed inaccurate.
1) You don't put that much more effort into crafting a higher q one. It's enough to build a new loom and plant only a few mulberries every 3-4 weeks to be close enough to top quality silk. Also it rises in a passive way, because most likely you would upgrade your looms, pots and tables with or without silkmaking, that's why charging extra pearl for each 20q is weird.
2) Prices set by other traders is a guide, but not absolute, especially when there are not many of them. In W5 you could buy a merch as close to top q as q160 is now for 4 pearls, in W6 the price was around 280pts (and it was already higher than q160), crafting process didn't change sinse then.
3) Bots make complaining about annoying crafting process insignificant, and ~80% of current major traders are active botters.
4) Everything lower than q120 now is probably bloodstained (talking about trading threads around here now, not lonely hermits you met in the wilderness), that means seller put almost 0 effort.
5) Most buyers don't care much about int and cha boost, the most important thing is inventory space, that's why price shouldn't change that steeply. Anyway if you want the price to be based on boosts, it should change at q40, q90, q160 and q250, not each 20. Difference between q10 and q30 is 7 int, between q140 and 160 - 3 int, between q30 and q160 it is 20 int, it's weird to pay one pearl per 10 int at the start and 4 pearls for the same 10 int difference later.
