I don't know how "sly" he is about it. Personally, at this point I think he is just a creature of habit and hasn't put much thought into "sly" tactics in probably 20 years. I'm sure much of the way he does things was at some point calculated for various reasons, but I don't think T's are particularly unique in the way. I suspect many of us design things for a deliberate outcome/purpose (or maybe that's just the teacher in me speaking).
