I'll copy the bit out from the message you're replying to:

I guess the clock speed isn't stated there - to get 1.3MIPS you needed
to run the GPS MA31750 at 10MHz but, being a space app, we weren't
allowed to, so we had to run it at 9MHz.

Quite a few probably. I certainly have on a few occasions. I wouldn't
say that the teams were that big, only 4 or 5.
