The further the capstan is from the back rail cloth contact point, the more
difference in capstan height will be seen with balance rail height changes.
It's pretty dramatic in grands, and pretty minimal in verticals. I would
find it hard to imagine a change in a vertical's balance rail height big
enough to necessitate capstan regulation, not being immediately noticeable
in key dip changes, even for a foot-handed clod like me. Of course, I'm
occasionally mistaken at ever shortening intervals.

Wim,  (this is NOT a trap - honest <G>) did you notice any such key dip
changes when you were pastafazizing after tuning? That would qualify as a
measurement clue.
