Re: Ask Chuck Kennedy
I think this would be an option available after a person brings up their current Ratings Detail. They would click the 'What If' button and their current round ratings and dates would be listed. They could then enter as many round ratings and dates as they wanted. No events even need to be listed or the round order within a day.
The logic for the calc would first eliminate rounds 12 months older than last date entered unless there were fewer than 8. Then the number of rounds to be doubled would be determined and which ones. If only one of two on a date was to be doubled, choose the higher rated one. Then, the SD is calculated to see if any rounds are knocked out. (This is the way Roger does it now but I think the SD knock out should be done first before the doubling.)
Then calc the average. The primary thing that's slightly different is that the round ratings have already been rounded. The other item is that the number of props may increase with people renewing since the time an event posted unofficial ratings and when the official ones are done. This happens all of the time early in the year.
