Cyber Monday - An index to gauge success

Time4Learning had its best day in history on cyber monday (monday after thanksgiving when the media reports that online shopping was HIGH). Is there anyplace out there that I could use a index to see if proportionately, I had a better day than anybody else? It would be great if they had an index by sector, say online elementary education or educational game sites? But still, any index which will tell me how I did proportionately to others would be useful. I did about 4x my usual business. Was that good?
