I think you should only comment on things you know more about.
The fact was that in the days leading up the meeting the forecast suggested that there would be very heavy rainfall throughout the day on Friday. As Friday dawned there was still suggestion that there could be some showers throughout the afternoon followed by very heavy rain arriving anytime after 7pm.
Not to make excuses but given the circumstances of very little rainfall over the last few weeks and an horrendous forecast, it was certainly a very tough situation. By the time the forecasts were updated to suggest that the rain would not arrive until later on (in fact, it arrived at 10pm), the opportunity to water to a sufficient level had long since passed. Just to add to a mix of the worst possible circumstances, there was a strong wing blowing throughout the day and occasional spells of warm sunshine. The track was watered throughout the day, though not to the point that it would have been had the forecast been good.
Of course the club will always endeavour to put out a terrific racing surface, unfortunately it didn't work out yesterday.
