Why is it wrong and what is the correct procedure to calculate the
percentage increase? Just curious!

Consider going from 30 to 33. It's an =increase= of 10% (an increase of
3, referenced to the starting point of 30). The =new= value is 110% of
the old value (100% + 10%). There are several equivalent ways of
calculating a percent increase, one is to divide the new value by the
old value, convert to percent ("per hundred"), and then subtract 100%.
In the AOPA case, 70.1/19.3 = 3.63 so the new value is 363% of the old
value. Since the old value is (by definition) 100%, when we subtract
that, we get a 263% increase.

I wouldn't blame Boyer; he's probably using an old pentium. "two plus
two is pretty close to three point something".

I nominate Jose to head the AOPA. He is at least capable of rational
discussion, unlike The Destroyer, who relies 100% (that means full
reliance, Phil, since you obviously are "percentage challenged") on
hyperbole, rhetoric, and faulty logic. All arguments The Destroyer
makes regarding user fees are easily rebuked. (The easiest is to
simply look at the contribution that AV gas taxes make to the Trust
Fund.)

But AOPA is a fairly powerful lobby, many politicians have vested
interests, and the FAA is nonaccountable to the nonflying public. The
battle to inject public/community rights into the use of airspace will
go on for many years. STN has made some nice progress, however.

Skylune out!
