Modal goal - Strad average

Balance is the key in aim to reproduce The Strad Sound. Average measures from "Stradivari's golden period" are from published articles. The selection of data is small and varies some depending on which articles you look at. This is my modal goal and plate weights, when measuring at ~6 % EMC in the wood. In Scandinavian countries B1 modes varies +/- 20 Hz between winter/summer.
