Control is the stat for crafters that give a higher % when you increase the quality when crafting, that ability when used will give you more control when you increase the quality witch will increase the % in the quality bar
So if my control is 100 and that gives me 4% when i use "Fine touch" (this ability just means you raise the quality) my bar will go up 4%, i then use inner quite and that raises the control by 15, so since my control is 115 that makes my quality % go to 5% each time i use fine touch. Does that make sense? Oh and all the numbers are just made up, to help explain it
It actually doesn't raise by percentage. (Yes, I realize you made up the numbers.) It raises by a set number of points (that's probably influenced by the recipe difficulty).
If you try using Basic Touch in level 20+ gear and compared how much gets filled numerically in a level 1 recipe and a level 20ish recipe rather than by percentage, you'll find that the numbers are a lot closer. The level one recipes have a 312 Quality (or so) while the higher level ones have ~700 or ~1000 or ~1100. That's why if you're finding that you can regularly pump out 150+ quality on each Touch, you can pretty much go back to the lower level recipes and turn any remaining level 1 components into HQ subcomponents easily.
Oh i thought the higher control the higher the % is for each fine touch, so control helps lower the number you need to get 100%?
Control determines how much Quality goes into the Quality Bar when you use a Touch ability. The next time you look at a tradeskill recipe, look at the bottom right. It'll give you a number. For a level 1 recipe, you should see something like 0/312. For a level 20 recipe, you'll see something more like 0/990 or something in that range.
So I take my level 30 weaver in his level 25-29 tradeskill clothes. My control is 178, and I take two recipes...let's say Dew Thread (level 24ish?) and Hempen Thread (level 1).
I use Basic Touch in Dew Thread, I will gain probably ~120 so Quality. But it needs something like ~1300 Quality to fill the bar. So that 120 is only filling < 10% of the quality bar.
I use Basic Touch with the same character in Hempen Thread and, for convenience sake in explanation, let's say I still get the same +~120 Quality. The Hempen Thread only requires 312 Quality to hit 100%, so now I've actually gained 38% of the Quality bar in one shot.
The next time you tradeskill, switch to the Battle Window. It displays your gains in numerical format, not percentage. (These are the same numbers you see floating away from you when you succeed.)
