Looking at some of the drilling layouts for PSA positions MB -pin - pap angles of 90, 105 and 135.
How does this fit in with the "no larger than 90" for the drilling angle concept of dual angle?

“Recommended “ no larger than 90 and no lower than 20. But one of the new radical layouts is like 15x4x35 for a smooth hook. I think he’s tweeking his recommendations with the new rule, but have not seen him recommend anything greater than 90. Unless it’s symmetrical, then it doesn’t matter apparently 105x33/8x35 is good.
