As i see score difference with my two games, doing things much faster dosnt give you really big bonus. This mean base difficulty bonus have high weight in result. Here my current game sample, u can compare with my previous game with same difficulty.
I can only say that I do not like the system of scoring. You illustrate it very good.
It´s extremly little difference for your first human on Mars - Sol 20 (3799) vs Sol 13 (4173) or between produced food (sol 14, 6260p vs sol 24, 5725p).
If it doesn´t matter more than a few % of the base-score there is no meaning in the scores. The only thing that will matter in the end is the difficulty. I would like to see higher bonuses for "finishing early" and higher malus for "finish late". To be honest - "Found water on Mars" is a rather bad milestone to score. It´s just luck and you can do it with a commanderprofile from day 1.
The only thing it looks like we really can manipulate is the evaluation score - as some sponsors make it poossile to beat the score by a high multiplications. Because of that I think "Covenant of the new Ark" is the sponsor with highest possible scoring - high difficulty and with a high population you really can beat the evaluation. But that will be my next game. Now I´m as said try to do the same with SpaceY.
If goal for milestone "built a dome" is sol 10 I would like to see a rather high bonus for making it on half that time, and a rather bad scoring for making it in sol 20. With the later goals I feel the same.
I´m looking at "Research a break through"
I got it at sol 17, 195%, 2223 points - equals basescore 1140 points.
Kdubya got it at sol 15, 310%, 3596points - equals basescore 1160 points
You ainyru got it sol 57, 535%, 3959 points - equals basescore 740 points
I guess we have a goaltime for sol 20 or 25 on breakthrough - but that I and kdubya only got 50% points for this finishing it at least 30 sols faster, or in 1/3 if the time looks as to little difference. I will continue to count my scores here, but I do hope that it shows Heimemont that we need a bit more of a bonus for doing things fast, anad malus for doing it slow.
tl.dr. time make to little difference on score, just the difficulty.
