Why do you mean by odd patterns.
3 bolt is normal and the 4 bolt is normal.
with them on the same plate the are perfect measurements.
even if the timing was off between the 3 and 4 bolt.
the 3 bolt hole is perfectly centered and the 4 bolt is perfectly centere.think of it as 2 different plates, one with 3 bolt holes and one with the 4 hole. If everything is right, thickness of the plate, centered prefect, and same with the 3 hole plate.
any reason each one would be out of balance?
then just think about mating both plates together, if each plate is perfect, if both plates where mounted together no reason it would make 2 balanced plates unbalanced.
