I don't understand your gripe with the 90% AMRAP. Do you think that someone will progress so quickly in the first three mesocycles that 90% of the TM will now be way too low of an intensity since one's actual max has outpaced the TM by too much?
Its just a needless addition to the program. What is the point in setting training percentages and then artifically lowering them by 10%? Indirectly via an adhoc adjustment. Either the percentages you have programmed are appropriate or they aren't.
