Any chance of telling us what you are doing to get those scores?
Just changing research order from previous games, ensuring that I don't actually research a tech until the latest possible time that I need it (e.g. Uni Translator not needed until 1st March at the earliest), and flying the economy very close to the wire (you still get full research output next turn even if you are at -499bc when hitting the turn button).
And, of course, spending about an hour on the first turn just fleeting and unfleeting my flagship so it gets unlimited movement - that despite the fact that it has a logistics value of 5, I have a logistics capability of 6, and there are no ships in the game that have a value of 1 with which to fleet it. Naturally, spending a turn or two researching Logistics would enable this - but you would lose so much elsewhere you'd be lucky to break 30K.
As for playing 1.80e - that is the version currently provided by SDC as the latest available. I now know it is possible to get a later version, but as I have 3 different gigantic maps ongoing I will not be updating until they are complete. There are also some very odd scoring examples with 1.80g that suggest to me that it could also be very bugged (just see the MV player in 9th place for examples).
