TGAB,
Thanks for taking the time to give your response.

The pattern seemed unique to me because of the duplicating tops and off races...
almost identical. I understand your thought about young, developing horses and still finding their niche, so to speak. The fact that AA is not adversely affected, I see what you mean that his efforts are not extreme either way. That makes sense that there is room for improvement.
You answered my follow up question before I asked , which is, would rest between races be a variable that could eventually lead to further improvement.
One other question, based on your own previous observations, would you expect that when AA, or any horse with this pattern eventually breaks through their tops,it would be a small new top or a bigger jump up?
Thanks in advance.
