The hardest thing for me to read about KA's sheet is the effect of the equipment change.

If the blinkers moved him up, that's not really development. The ability might well have been there as a 2 year-old, and he's just now running to his potential. What would have his 2 year-old top have been, had he run that race with blinkers?

That's pretty much unknowable, but I can't make the assessment of his developing too much too fast (or not) without that info.

His workouts have been pretty meh, but EQ's have been even worse, so who knows.
