Pinion angle question

I just drew it out and I'm backwards. If the perches are level and the pinion is at 5 degrees then you put the pinion level the rear of the perches would go up! Right now my perches are at 6 degrees with the back down so I I need to set the pinion at 11 degrees. 6 to level the perches and 5 to get my pinion angle. Correct?
