Well, a Golden Age increases your hammer output a good bit. I took the 70-100 turn number as being 1% of the total game turns, as IIRC we have ~100 Great Wonders.
I was not saying build a wonder in a golden age just that the time it takes to build a wonder should not be longer than the time for half a golden age. Especially since most wonders, including The Pyramids, were built in much less time than the time in one game turn.
