Is Rep gained from scores variable or is it purely a function of the Tier of the faction you are messing with? Could you gain +1 Rep for a particularly daring score, or -1 Rep for a particularly tame score?
Also, if you are trying to pin the score on someone else to reduce Heat gained and/or reduce faction Status lost, does that affect your Rep? Doesn’t gaining Rep from a score imply that everybody knows it was you who pulled it off?
Finally, what’s the fictional explanation for spending Rep to take additional downtime actions? The only thing I can think of is: you’re spending extra time between scores, so word of your exploits is beginning to fade. I think that’s a perfectly fine explanation, but I’m wondering what else people have come up with.
