Daily Sales Rate. I think it is an approximation of how many shirts per day sold in the last week. A shirt with a high DSR could indicate that it will rise in the ranks as it is selling more this week.
Money can buy happiness. Toys bring joy. It just doesn't last long. That's why we have Woot!

Imma gonna disagree here.
I've been tracking Deltas on and off, that is the CHANGE in the DSR, and Narf's RealTime is Actually really accurate for ending position, barring last minute jockying.
See Narf's RT-DSR doesn't Take into account Opening Day, it only counts sales after midnight on Debut. And while this is a much smaller pool of days for Newbs (less than 14, typically 5-10) the numbers are still PURE. If you've got an RT-DSR of 20.35 your DSR at Close will be about 20.
Here's an example of the difference
A Friday Shirt sells exactly 2 shirts every hour. On Thursday at Midnight Narf pulls numbers. The shirt has 48 sales for Saturday, Sunday, Monday, Tuesday, and Wednesday, for 240 Sales.
DSR is Sales/Days so:
RealTime DSR = 240/5 = 48
WOOT DSR = 240/9.5 = 25.26
Here's the Catch -- the shirt keeps selling 2 shirts an hour, so Every time we look at RT-DSR, it's ALWAYS 48, but the Woot will be climbing 25.26, 30.32, 35.67,40.42... until at close (noon monday) both equasions look like:
456/9.5 = 48 DSR
Now, going back to what I initally said "barring last minute jockying" my tests show that my method is accurate 6 days a week. Mondays are HELL on my equasions. This is because people aren't buying in normal patterns, they're buying in frenzy patterns. Also, position on the list is real variable, but it's only felt in a very small range (19-22) and then it's a measurments of single shirts, not big units.
So, tl;dr - Order shirts by RT-DSR and you're looking at closing position for 1-17 and 23-25.
