Nice editorial

The thoroughbred descends from middle eastern stallions. There is a lot of dirt in the middle east. It's pretty simple.

Sure. If you ignore that the breed wasn't developed in the middle east, but developed after the three Arabian sires were imported, and was developed primarily in England from fairly common mares. Pretty simple that Arabian sands were never involved. Let alone dirt.

What does records from Harness racing, grass racing, European racing, Australia or jumping have to do with the lack of breakdown stats from American dirt tracks?

There's breakdown stats on American tracks. For example, how about the NY tracks in the 1980's? Compare America to Europe, to Australia. Flat to hurdles. Harness. Lots of good info.

And since the jockey club's Equine Injury database is only 2 years old and still doesnt have cooperation from all tracks I find it hard to believe that there is a whole lot of accurate data from prior years.

Current data has zero bearing on what was available before it existed. As I said, go read the multiple scientific studies on PubMed. You know they are there. They've been mentioned before. And mentioned multiple times when artificial surfaces first were discussed. In fact, those stats contributed to the development of artificial surfaces.

And the initial findings of the databank is there is little to no statistical variance between breakdown rates on different surfaces.

As someone who is knowledgable of the concept of "statistical significance", you know that one final quarter affecting a years data doesn't give you much of that, does it?
