Thanks CP. This is a start. This means that he looked at the time rating and added extra weighting to that impact value. It also means that he considered this going compared with previous going. OR did he? If his ratings came out before the official grading of today's race, then this not possible. If they came out after, then it is a case of when. If it was immediately after it is possible that several different scenarios were made and the appropriate one posted, or the ratings were put together after the grading which definately implies a formula. No matter how good you are, it still takes time to put a set of ratings together.

The ratings that I used in the past Larry T and Gunther R only did ratable races and they both commented on the time and effort. Larry is a Melbourne only service, and Gunther would only manage at most 10 races SBMWA.
Interestingly both commented on the effect of the EF. Beton
