Estimating market size (Re: Change the name)

Just for a fun, I played with some market size estimation.

It is said that in Japan on Linux platform, PostgreSQL/MySQL/Oracle
has almost even shares (I would say 25% each). PostgreSQL's share in
US is probably less than 5%(correct me if I'm wrong). Now population
of Japan is 127M, while US's is 300M. So I could estimate number of
users ratio in Japana and US as follows:

Japan/US ratio = 127M*25% / 300M*5%
= 2.12

So may be I could say that number of PostgreSQL users in Japan is
twice as many as that in US?
