Bait, bullpoo, or both. Who told you this ? You're roughly
correct about the base tension, assuming your idea of
the shutter's rest position is written in stone. To get past
the guesstimate, we have curtain velocities and shutter
speed testers. But breakage ? Surely you have more
respect for German engineering.
And your statement about Japanese SLRs is off. Spotmatics
came out of the factory with no more than 2 1/2, 1 1/2 turns.
Roughly speaking, of course.
If the camera has never been serviced _properly_, a CLA
is in order. Period. Just do it. No more worries.
