sorry I didnt get back to this yesterday, had a lot going on.
So, in some ways I don’t find the charts particularly easy to apply the way you’re describing because of your exercise selections. The main reason INOL is calculated, from the way I understand it, is fatigue management. Actual fatigue resulting from, say, a 70% OHS should not be comparable to that of a 70% front or back squat. So if you’re applying the same formula to each, I don’t see how it can work for the outlined purpose.
Here’s how I would approach it. The main purpose of practicing front and back squats will be to continue to develop stronger legs. At your level, that should be the case. I think I can also rightly assume that practicing OHS will be more about technique, and you’ll be using substantially lighter loads for your rep work. I would apply the INOL to the ‘main’ lifts, and accessory movements like OHS can be gauged more by feel. If they’re incredibly taxing at whatever volume you’re performing them at, back off a little bit, either on the weight or volume.
