That test compares them to modern violins. Maybe comparing them with their contemporaries would provide more accurate results? I know I prefer the sound of a Guarneri violin, but Strads are reputed to have better piercing power for carrying to the back of a concert hall, which was definitely an advantage in the days before electric amplification and computationally modeled and strategically baffled reverberant chambers for maximum audio enjoyment over the widest possible range of listeners.
