Yes understandable, that's a much better idea.
I soldered mine to the middle edge of the copper link bars in the last 48V LFP I made.
I think I mentioned that before, but as it was a new build I also soldered the BMS leads at the same time, put shrink-tube over the middle, done. Really nice way to go with no stupid eyelets or screws needed.
In my case, the only thing I look at now when checking the cells in Active balance time is the difference voltage. That is stable as it's a snapshot of the HI/LO cells voltages, it's read when the Active balance logic pauses the balancer to read the cell status prior to selecting the next balance pair.
Look forward to seeing if you notice any difference.
Not sure on the cycle count, I wonder at what upper and lower SOC point does the BMS logic decide it's a valid cycle and increment the cycle count
