I have *not* performed 300, or even one, such test, but as a practicing S.E. specializing in residential seismic upgrades in the Bay Area I have to ask: How much practical difference does 3/8" or even 1/2" deflection make when the objective is collapse prevention?
I realize that expectations may differ for the performance of new, and probably expensive, construction.
