CrvDeviation accuracy

While reviewing Bug: Rhino reports false deviation values
I noticed a 11 mm length where the deviation between the 2 curves is greater than 0.78, even though _CrvDeviation in both V7 and V8 is reporting 0.77 as the maximum. (The model’s absolute tolerance is 0.001.)

Yes, I see this too and I have created a YouTrack item for it https://mcneel.myjetbrains.com/youtrack/issue/RH-83592
