Actually, I'm glad you brought up the issue of focusing-screen misalignment. I don't know how big of an issue it is with Hasselblads, but it is a common cause for focusing issues with many cameras, rangefinders and SLRs alike, and often the last place where people look for the problem.

In Hasselblads, the focussing screen position rarely causes problems.
If anything body length and mirror alignment are the 'usual suspects' when focussing differences occur.
Could also be (the most common cause) a focussing screen that has been dropped in upside down.
