Well Falcon, if you get to the point where you can do 1 arm push ups wit weight added on to you, then you is gonna be sporting some impressive delts and tris ma man! By the way, do you train on these push ups every single day?
if i do half ass volume one day on pushups i usually follow next day with either high or half ass volume, i just do as best i can but i dont try to max volume both (pushups) and. ( dumbell/barbell hacksquat/squats) i usually pick on or the other to max volumize on
for ex
day one max volume pushups/ half effort squats
day 2 half effort pushups/ max volume squats
day 3 everything half effort or sub max volume
day 4 everything half effort or sub max volume
thats basically how it rolls. some days everything ends up being half effort . I consider anything less than a Personal Best is half effort. So im always trying to go up in weight or sets or reps or otherwise its considerd half effort
it usually takes a few days till i break a new record
