Hi Brendan,
I do not want this to be a "what if" exercise and only make this brief comment.If we are measuring batches of Widgets " two batches of 60 - 100 give a very different result". No they will not.
yes they did. The bathurst 2yos V menangle. See my blue writing above on ABitDustys post where the % of horses at ages who started at two are very different.

Back to the original argument of 2 year olds lasting etc. We all know the old saying about statistics but they are only valid if all data is constant.
and of course ABitDustys stats weren't exactly constant but the above re skewed still stands
