I don't really have any lack of turns to cash/explore by about the 15th-20th day in the reset, so I'm not sure how useful getting CS up early is (I mean to say exploring for 5 turns at end of the day on the 16th is basically equivalent to building 5 CS, that extra 50 acres is fairly marginal). I could see the argument that grabbing at 1.9k->more production up faster (since if you mass X you don't build a new IC until AFTER all the exploring) ->more $$ for tech early->more production->more $$ for tech->more production->... in an endless loop:P
