Quinn McConnell takes a narrow win over Brynn Siles in a merged Liberty Bell - St. Vrain meet, with time adjustments.

Yes, you really would like to know what a merge of Liberty Bell and St. Vrain would look like. The next best thing to having all these teams in the same meet would be having a reasonable merge of the two meets.

If you've been around for a couple of years now, you know I try to do a merged scoring of St. Vrain and Liberty Bell. To do this, we need a conversion factor to convert Liberty Bell times to St. Vrain equivalent times. You can't use the same factor year after years because conditions differ year to year.

But, we do know that a lot of athletes who ran at Liberty Bell also ran at Arapahoe or Centaurus the week before. The same can be said for a lot of athletes who ran at St. Vrain. So, what we do is take all the athletes who ran at Liberty Bell and Arapahoe and calculate a conversion factor between those meets (actually, I do this separately for boys and girls under the theory--not too far-fetched--that the differences between the two meets will reveal themselves differently between boys and girls). I do the same for Liberty Bell and Centaurus. I do the same for St. Vrain and Arapahoe. And, finally, I do the same yet again for St. Vrain and Centaurus. Then I compare the conversions from Arapahoe to Liberty Bell with the conversions from Arapahoe to St. Vrain. And, I do the same with conversions from Centaurus to Liberty Bell and from Centaurus to St. Vrain.

If I've done my math carefully and correctly along the way, I should know be able to derive a reasonably accurate Liberty Bell to St. Vrain conversion. I'll spare you any further details of the calculations but will tell you that multiplying Liberty Bell boys times by 1.041 should give us a reasonably accurate conversion to St. Vrain times. For girls, the conversion factor is 1.047. 

To give you a less abstract idea of the magnitude of the conversions, an 18-minute Liberty Bell boys time would convert to about 18:44.3 at St. Vrain, for this year. And a 20-minute Liberty Bell girls time would convert to about 20:56.4 at St. Vrain, for this year.

Armed with those numbers, I loaded all the St. Vrain times and all the converted Liberty Bell times into a single file. To help keep things manageable, I cut boys times off at anything below 20 minutes. I cut girls times off at anything below 24 minutes. Then, I team scored the whole mass of results.

For athletes who ran in both meets (and there were a few), I used Liberty Bell times.
