Yes it is.
I start with thesis that opus 3100 charge battery to 100% of capacity because it is best charger for Nimh which I can find in this moment and with my possibilities.
If I was wrong I hope that I didn’t make big mistake?!
Like Mandrake50 wrote, normally you have a little difference at every run you do. And things like directly from charge to discharge or discharge 30 Min after charge etc.
And some cells differ more than others, you might have also different values if using different slots
