I agree that it's not about the numbers. What you can do with your knees is far more important.
I didn't go to PT and my ROM has never been measured, but I can do everything I want to with my knees. I estimate they both straighten fully and bend to over 125 degrees.
My surgeon doesn't care about the numbers, either. He looks at my knees and says "Show me what you can do."
Have the PT measure your ROM whatever way is easiest for you and make sure that it's measured that way from now on. The actual number isn't important. It's more important to confirm that you are continuing to make steady progress.
