It was pointed out to me by someone at Brightcove that I would fail a grade school Math test. I've been saying that the Flex 3 SDK improvements give a 20% compiler speedup. So how did I come up with those numbers? Well, if you look at the numbers I provided and add them all up, you can get a percentage:

(101.5 - 81.5) / 101.5 * 100 = 24.5%

Hmm. So that's not how I got the number, because that's faster. What if I averaged out the different scenarios?

(13 - 8) / 8 * 100 = 62.5%

(41.5 - 34.5) / 34.5 * 100 = 20.3%

(47 - 39) / 39 * 100 = 20.5%

(62.5% + 20.3% + 20.5%) / 3 = 34.4%

Well, that's not right either. So how did I come up with that number? I don't know. But I like the new numbers better.
