Well if he wasn't using standard touch or advance touch and has no access to hasty touch then inner quiet is a waste without landing 6 or more basic touches. I don't see him landing more than 6 basic touches no way....
For those confused. Inner quiet grants 20% bonus in control AFTER a successful touch which means at a cost of 18cp to activate you'd need 6 successful basic touches JUST to break EVEN on quality as if you hit 7 basics touches (no iq). Since no BB...he would not be plus until he hit that 7th basic touch while under the effect of IQ (total of 144 cp)
Note: another perk of IQ even though you don't have hasty touch or BB is it saves on durability!! I just realize you're 53 so you have precise touch which is basically an OP proc (arguably the single best skill added since heavens. But it only benefits with IQ)
EDIT
Bad math!! Yes IQ gives bonus of 20% of your control per successful touch; however in crossed out scenario above you would ONLY need 3 basics touches under Inner Quiet buff to reap the benefits using IQ.
Here are the numbers:
your control linearly correlates to your touch quality so a 20% increase in control translate to a 20% in your touch of choice
scenario 1: NO IQ; control = base; 3 basic touches; 3 steps;total quality 300%; 54 cp used
scenario 2: IQ active; control=base
step 1: IQ (18 cp);
step 2: basic touch (100% quality, 18 cp, grants bonus after)
step 3: basic touch (120% quality, 18 cp, grants bonus after)
step 4: basic touch (140% quality, 18 cp, grants bonus after)
end of scenario 2: IQ active; control=140%*base; 3 basic touches; 4 steps; total quality 360%; 72 cp used.
NOw comparing the two scenarios:
in terms of durability-steps taken the second scenario has better quality progress for the same amount of durability-steps;
but in terms of quality/cp!! the first scenario is still plus over that of the second. the quality/cp will not reserve between the two scenarios until 4th touch! So optimally IQ isn't a win-win-win (quality-cp-durability) until the 4th successful touch (IQ, touch1, touch2, touch3, touch4, ...)
moral of the story instead of 6 touches IQ is plus after 4 touches!
