100 reps program

I’m trying to get a little info from those of you who have done Chad Waterbury’s program. My main goal that want to gain from this is improved strength endurance. So my question to those of you who tried it, to what degree did it improve your strength endurance? Also, if the muscle I want to improve is my delts, would I perform the 100 reps on days that I workout my back(chins and rows mostly). And I ask the same for my calves on days that I run or jump rope. I know this is alot so I really appreciate any help I can get.
