Top Rank,
you must live in a "perfect world" and if only this was the case.
The rest of we "battlers" depend on our daily/weekly earnings to put "food on the table."
Therefore, we have every right to expect the officials to advise we "mortals" of expected/anticipated change of riding tactics.
I heard a commentator state something to the contrary earlier today....but then again...what does he know...?

Cheers.
