I would say used to know. Now the newer sups are all DTS trained. While they are good at explaining the theory they lack real world experience until they get enough hours on the street teaching others. Even then most go a few years before they can even compare to the skill level of an average rookie feeder driver. More often than not the senior feeder drivers fill in the holes in the training.
Both of my training supes came from feeders. One was a driver for 15ish years, the other for 5. My center manager also came from feeders and did a ride along while I was doing some daytime pickups.
We used to have high seniority guys do the productive training. I can see where that would be great if the guy was a good teacher, the problem is that long seniority does not automatically mean good teacher.
