Ellipse of having minor axis 0.692200628 and major axis 1.444667861 has circumference 6.9229....... which seems quite close to be minor axis 0.6922006.... multiplied by 10 but deviation occurs at 6.922''9''... after ''22''? Why?

What you have here is a coincidence!

You might also notice that if $a = 0.692200628$ and $b = 1.444667861$, then we have $ab = 1.000000000635616708$ which is remarkably close to 1. This is also a coincidence, unless there is some reason why these numbers should be connected in any way due to the method by which they calculated in the first place.
