Those readings are not necessarily accurate, at least some of them. Pulleys can be bent, and you show the angle reader on the output shaft which "wiggles" with no support with no yoke in place Also on such items if the angle finder is not exactly at the top of the pulley or shaft, it will not read correctly, either. In other words the angle finder axis 90 to the angle you are reading must be "plumb"
There are a few things that are either parallel or perpendicular to the true crank centerline Some may not be accessable easily. Water pump/ timing cover face (machined surface after gasket is cleaned off), crank snout before you put the balancer/ pulleys on, and the pan rails, either engine or automatic if properly mounted. Some U joint caps are flat, so if you have a yoke with a U joint in, you can check off one of the caps. Again, make sure it is rotated "plumb" either top or bottom
Without checking such as the pan rail against the TB mount, I have no idea if they the TB mount is on crank centerline
Any cast (not machined) surface such as the top of the timing cover ---is suspect
