I was only comparing the increase in revenue compared to the increase in subscribers.
What I took were your additions per month from your post in January. You had 3000 subscribers through the end of Sept from the SEC filing. Then it took a 750 increase in October, November, and December plus an additional 270 for the CC trial that began in December. I pushed the revenues back a month in case the subscriber had signed up at the very end of the month and were on the free trial. So the October additions wouldn't pay until November and the November additions wouldn't pay until December. December would not be seen on the most recent filing.
Here's what I came up with:
October 750 adds @ $10/month (assuming no churn)
October Revenue = 0
November Revenue = 7,500
December Revenue = 7,500
Total from October adds = 15,000
November 750 adds @ $10/month
November Revenue = 0
December Revenue = 7,500
Total from November adds = 7,500
Total from Oct & Nov adds = 22,500
I took the YTD revenue from the most recent filing and subtracted the YTD revenue from the Q3 filing to determine the Q4 revenue. Q4 revenue was approx $9,000 higher than Q3's revenue but we had doubled subscribers. Just trying to figure out how it all adds up. It could have been that most of the adds came in December instead of gradually over the months.
