Jim -
One, simple, 'go/no-go' test would be to push the backchecks far enough back to remove them from the equation (might have to take off the sost. rod - don't forget to put it back). Note any differences.
You can also experiment with varying the height of checking, and, while you're at it, up/down weight, but you've probably already done that.
Are you a competent-enough pianist to provide an objective assessment? (I'm not). Wondering if different trill techniques would provide different outcomes.

Subject: Backcheck involvement during a trill
Anyone know of of any high speed videos of a note in quick repetition?
My interest is in the repetition speed of a single key/note during an extended trill. I'm not as interested in the rep speed of a single key repeated note repetition. This because a trill is much more common in practical use than single key repetition, and each key will be repeating slower than the single key repetition.
I'd like to see how the backcheck is or isn't involved in keeping the key in phase with the shank/hammer, in fast repetition.
