I did 3 weeks of laddered pullups buried inside the clean & press sets. I was using Pavel's Fighter pullup progression from a 3 RM and was up to rungs of 4,3,3,2,1 when my left elbow started doing something I could "feel" after the 3rd session of the week. So I dropped pullups while continuing Strong!! in order to be sure it was the pullups causing it. It was. For a 50 year-old like me, it was too much. I suspect the extra demand of the higher weight plus double KBs I'm using for Strong!! vs. ROP plus pullups simply demanded more than I was able to recover from, so by Friday my elbow began to warn me of it. The good news is that I now know what volume of pullups I can tolerate - at least if done in concert with another program. Advance with caution
