Jimbo-- there are other strings, you might be able to find them, but they cover pretty much the same ground. Again, if you can figure out the right query (tougher than it looks), we can run it easily enough. But a) so far the figures seem to hold up on neutral surfaces, and b) there are far fewer really bad figures run on grass, for whatever that's worth.

Again, the possible reasons for less improvement (if it's true) could have to do with the slow paces, lack of drugs, pedigrees slanted elsewhere, etc. But wo knows.
