Vibration right off idle

Ok, so I got new biscuit rubber mounts and the motor is sitting level side to side and so is the trans.

I wanted to get your guys opinion on where to measure for pinion angle? For the transmission, I've measured on the pan rail and the end of the tail shaft and I get two different angles. Same goes for the pinon, I measured on the bottom flat, and also the flat of the yoke. Once again two different angles.

If I go by the trans tail shaft I get DOWN 2.5* and the flat bottom of the pinion is DOWN 3.9* I used the Tremec App and it will only go green if the pinion is at a max of 3* DOWN.

What I don't understand, is all I read is that the pinon needs to be parallel with the trans under load. To be parallel wouldn't the pinon need to be at 2.5* Up under load?
