Hey Jim,

SNIP
you said:

If it is a type similar to a last word, where the pointer
swings in an arc, then the dial reading will indeed depend
on the length of the pointer from pivot to tip. The longer the
pointer, the more sensitive it will be, ie, for a given tip
deflection, you will see a bigger dial reading.

Hmmm..

Want to have another run at this? The longer the lever, the LESS
sensitive it will be. Smoother for sure, but less sensitive.

Take care.
