Is all weight pushed equal?

But where do you figure "Time Under Tension" ? or don't you ?

I was wondering this as well after reading the post again, obviously it takes twice as long to do 18 reps as it would to do 9 or so.

In my case I do sets every other minute regardless of reps, so total workout time would be the same basically but the TUT would not.
