was easily predictable

...I am surprised some members with supposed superior intellect did not fall within the correct day slot in late November 2011

....simple formula......
number of members @ 01.01.2010 X the increase of members on an ever increasing monthly cycle FMAMJJASOND [January 2010 is naturally taken from the equation] for 2010 divided by the inverse of the same proportion of increase in Year 2011 = 7000 members

Using this formula

I predicted the 7000+ value on 28/11/2011...but have not looked & back checked the result
One must understand rounding values [0000000] [0000001] can alter the result by a day or so.........
