This kind of test proves very little other than the fact that, yes, there are good modern instruments being crafted today. Are they as good as the Cremonese instruments? Wolf Garcia has it exactly right; it is the feel of the instrument to a particular player that matters. This merits some expounding as there is a lot more to "feel" than may be obvious:
Every player looks for different traits in an instrument's response characteristics ("feel"). Some players like a very responsive (fast) instrument, while another player may prefer an instrument that needs to be coaxed to some degree for it to respond. It is a very personal thing and a kind of relationship between the player and the instrument. As a general rule modern instruments (not just violins) tend to be more responsive than vintage ones and this goes to the appeal of the Cremonese instruments. The Cremonese may need some extra coaxing to respond, but the reward can be layers of harmonic complexity and color that many players feel cannot be found in many modern instruments. The most important aspect of "feel" is what some payers call the "sweet spot". The sweet spot is the "spot" at which the instrument's inherent "requirements" come together (hopefully) with a player's individual technique characteristics (and this includes the player's actual physical traits) to let the instrument fully express its potential. When this happens is when the player can, in turn, fully express musicality. Importantly, and the reason that these tests are pretty pointless, is that finding that "sweet spot" does not happen in minutes or even hours. A player needs to live with an instrument for some time in order to understand it and how that particular instrument's personality meshes with his/her own technique and expectations.
