The real solution to this is to attenuate their effective voting stake in the auction, not their reward. That is to say, if you vote at the 90% RA mark (3.3 minutes in), then for the distribution of curaiton rewards, your vote should count likeyou had 10% of your SP. So a 100K SP voter in the third minute shouldbe treated for distribution purposes like a 10Ksp voter.
Yeah, I like that idea. Maybe this should be explored more. I'm sure we'll chat about it.
