Based on this I guess we should also expect head tube upper ends to be cut as low as possible on track frames, with only the bare minimum of extension above the top tube.

The NR head set stack is about 39.5mm. The same vintage Pista version was about 33.9mm. A difference of about 7/32". Not much but when you're looking for the Nth degree of advantage maybe enough. Being a small guy the stem/bar height can often be higher then I would like already so I can appreciate the lower stack, not that I ride the track. Don't let your frame of reference make you think that the Pista came second, dimensionally. If I had more historical knowledge I might be able to make the argument that the Strada's 3/16" balls were the improvement from the then standard (5/32")... Maybe trackies talk about how heavy road stuff is, unnecessarily so for their track needs. Lastly this is racing equipment. It doesn't have to last longer then the event. Just ask Lotus (F1 campaigns in the 1970s)about building to the edge.
