when something says to work to a single, what %'s of your 1 rm should you hit below that and how intense should it be. id assume that maxing out on effort in earlier sets would be bad, but i would think that you wouldnt want to just do 1 with light weights as this wouldnt really prep your CNS. so should you do like half for a few reps, 3/4 for a few, 90% for one, and then 95+% for one?
