The decline continues through 30 days, with anomalies now at

DCA +10.2

NYC +9.0

BOS +8.8

NYC sitting at 51.3 and with today's likely mean of about 42 factored in, month will barely fail to break the record (51.1) by finishing 51.0, based on 1539+42 = 1581/31 = 51.0. Would need to average 45 to tie and 48 to break (depends on rounding mainly).

Anomalies will drop slightly as today will be hard pressed to produce positives let alone +10s.

But what a wild ride this has been through record territory, against what many would consider the most difficult record to beat (monthly, for weekly would go July 1936). It's more or less a tie goes to the monthly max situation. March 1945 remains the bigger kahuna that way.

If I extend the provisional scoring (see Jan and Feb contest threads) that I used, March would probably not give the same range of scores as the official system. In JAN and FEB the scoring was based on errors within 5.0 deg of the actual values, a more lenient range than we had before the new system. And that seemed okay for JAN and perhaps a bit early on the cutoff for FEB, but in March we are going to see a range of scores that are way too low and probably won't match up with the correlation stats, so I will score this and any other month where the departures are >6.0 on a more lenient scale as follows ... for DCA, scores will be on the basis of 1.5 points for every 0.1 above 1.5 and for NYC and BOS, 1.5 points for every 0.1 above 0.5 ... this will max out at +8.2, +7.2, +7.2 ... anyone who went above those values gets 99/100.

You can see the provisional scoring reports for JAN and FEB in those threads.

I will try to update this month later today. Then some day we can compare this provisional method to the stats generated by Mallow's method.

I have scored JAN, FEB and MAR provisionally for the interest of participants, and as explained in the JAN thread, this is not meant to replace the official scoring but just an attempt to show the scoring from a fairly similar technique. We'll see later how similar it actually is.

Scoring for March ... see previous post for explanation of more lenient point deductions in March due to the extremely high outcomes, which would have given some fairly good forecasts very low scores. The ranges have been extended by 50% which is going to allow forecasts in the +2 to +5 range to score reasonably and also increase the scores of the closer forecasts. The chart below shows the March scores and those are followed by the JAN and FEB scores with a running total at the end. The order below is for March totals, ranks for the annual totals are placed beside the current top ten. Scores in March with time penalty deductions are marked with an asterisk * and so the numbers do not correspond to totals of the three months (a penalty of 1% per late hour is applied). The top 20 annual ranks are shown.
