I think that is a misinterpretation by Murthy.
What the AILA statement (which is what Murthy are discussing) is different. You can find the AILA release in
post #7549 on page 302.
According to CO, Porting used 2.8k
in March 2012 alone, not in FY2012 as the Murthy article says.
When talking about Worldwide usage, the statement was also about March 2012 consumption and said
Even if the figures are taken at face value, Worldwide porting numbers were about one third of those for India and Chinese porting was about one sixth of the Indian level. March 2012 may not have been an indicative month and CO's figures are at best a "guesstimate", since he acknowledges that nobody is keeping track of the actual numbers.
