This is a very interesting debate which I have had with many through my years with SCV and teaching at various high schools. I believe that the root of this "issue" is that everyone has a dfferent idea of how the Dr. should be used and interpreted by the performers on the field. Its just like different brass methods, match vs. traditional grip, and straight leg to bent.
The way that we used it at SCV while I was there, it may have changed now that there is a new DM and a new percussion and brass staff, is that the Dr. was a way for the performers on the field to see and feel the difference in time between what they hear (Dr. beat) and what they see (conductor) from wherever they are on the field. So.... this means that I would conduct to the Dr. Beat. When I would do that, the performer will SEE me conducting BEHIND the beat which they are hearing. So when the Dr. Beat is on, they would play with the sound of the Dr. beat and memorize what it looked like to play ahead of my hands. So for them, they must play ahead of what they see from me when the Dr. is off. Its all about relationships. So it is a tool for the performers to learn this relationship so that the sounds will line up when it reaches the front of the field and you in the audience.
This is only one way of thinking about it, but I think that it works great. I would also plug into a metranome (the big Vic Firth headphones work great with a Tama or a Yamaha Click Station, Dr. Beats are actually too soft to hear) which would keep me honest tempo wise. It also was a great tool for me because I could comment to the staff on speciically what sections of the corps were slow/fast and when it was happening. This was VERY usefull.
Again, tons of different ways of doing it, this is just one way that works =)
