My circle is off a whooping 1/8". What a nitpick. As explained to you, the damage was located using the windshield as a guide. The width of the mirror is secondary.
The Garage Photo is difficult to match as it has zoom and very little perpendiculars and straights. The camera angle is depressed and the field-of-vision is unknown. In time, it could be worked out. Much easier to maintain some precision with a photo like the Altgens Photo.
As I predicted, you have now created a new error. It is certainly better to leave the scale of the mirror alone as doing so preserves its match with the Altgens Photo. Personally, I can't see how your new version has the "Nebula" shape corresponding with the windshield damage disc.
So you have never done an original mapping of the damage area on the windshield to see if it corresponded to the "Nebula" shape in the Altgens Photo. You simply thought it did.
This isn't a 100% exact science but if your claim is that your initial diagram constitutes some sort of proof, it cannot if that rear view is of the wrong dimensions in the 3D model (when everything else is at the correct size).
Don't forget that the zoom I posted earlier in the thread clearly shows starburst rays of light reflecting off the bullet impact
in front of the mirror. What we see in Altgens 6 is the bullet impact (with a slightly darker centre) directly aligned with the glimpse we have of the light coloured bag that the woman is holding.
Also, even in your diagram, we can see that the downward crack in the glass is
in front of Kennedy's shoulder!
Here's the image that I posted earlier:
So this bullet impact on the windshield obviously happened at the same time as he "magic bullet" shot.
