i get 17 out of my first set for BW pull ups, then 10 for the next, then 8 for the 3rd.
about a week or two ago i was only getting 12 or 15 for my first. granted i could probably get more total volume out of these reps if i didnt go to fail, but i like pushing it each set so it doesnt seem like im 'wasting' the first set.
basically, i think with BW exercises, going to fail if its at the end of your workout will stimulate your muscles to get stronger faster (provided you can adapat to that type of training and can do it every second or 3rd day or whenever you do program B for SL) as your body doesnt want to be weak again, so it uses hypertrophy and adaptation (both musclular and neural) to get stronger and bigger so you wont be weak next time. kinda like drinking- your body will try to build up a tolerance if you binge, because it doesnt want you to get drunk and blind next time so youll have to drink more to get the same effect. its the same with weights but its obviously beneficial for your health.
but having said that, everyone is different, so try both out and see what works for you.
I can see why not going to fail can help also, just thought id back up the 'go to fail' side.
