Emergency Build from the Start?

[Saxon]

As the longest serving poster who still asks newbie questions, I feel I have to ask another one.

When starting up a game with ancient race, is it worth putting your ship yards up to emergency build? My thought is that you will have slower yards for a while, but hopefully you will get the benefits back by cranking out colony ships for the first few turns and then having many planets building and producing.

I am in a two player PBEM and the scores are turned on. I suspect my opponent is doing the emergency build plan (Hi Gerry, if you are reading this) and I wondered what people though about it.
