Actually your input revealed that this functionality was slightly broken and has
now been fixed.

Yep, you're right. I went back and compared my code with yours and discovered
that I was doing this:
Angle1 := 180*pi*arcsin(sqrt(PointDotProduct(temp, temp)));
vice this:
Angle1 := 180/pi*arcsin(sqrt(PointDotProduct(temp, temp)));
Fixed now.

This was reported by Willy and has been fixed.
