If someone were obsessive about constantly adjusting the stops, he would eventually wind up with the wheel at the front of the DOs.

This Masi, see above ebay link, (I had to work Masi into this discussion) belongs to Gianni Pergolizzi. Looking at adjustor screw and the rear axle, I can conclude that 1) if the Campagnolo dropout is similar then adjusting forward to the limit will not result with the wheel in front of the DO and 2) that Gianni is obsessive.
