Another trick is to go under the hood and pull on your cable sheaf where it goes into the adjuster. You can feel the play there if it is too much (old mototcycle trick). My Spec 2 is adjusted in the middle hook of the quadrant and it is really tightly adjusted. meaning no flop in the pedal at all and no play when you pull on the sheaf. I feel some resistence right away when I first push the pedal and then it gets stiffer as it actually works the clutch. It is shifting just fine and not burning the clutch up at all. If I am a little too tight on the play it is on purpose to quiet the TOB and to even the clutch fingers on the noisy/chattery Spec. But, it grips really well and I ran my second best ET ever at LACR under bad altitude density with a headwind Friday night. For the most part, you want to eliminate excessive free play. Usually if you adjust a little too tight, all you will do is prematurely wear out the TOB. If you go way too tight, your clutch will slip, which is not good. But, with your torque, one would think that you could detect clutch slip in at full throttle in 6th gear from 1500-2000 rpm very easily.
Also, I noticed that I can heat the tires really easily with the Spec as it is not slipping at all. This could be another test.
