This is a theoretical, not a problem.

The primary is calibrated with a hollow 10gr pin, 160/230 spring. 47deg beige.
Holds correct shift rpm. ( a basic stock early summit setup)

I change it to a solid 16.5 gram pin, what would it take in the secondary to make it hold the same rpms?

I know from experience that a stiffer primary spring can do it, also a change in ramps has worked for me. Could a change in the secondary do it? any rules of thumb for grams to degrees?
