I have a suggestion. (not my area)

Is it possible that the trail will only include voters who pass the threshhold? Or, a voter sets their vote to only trail every second or third curie vote so they can increase the % of the vote without draining SP. I don't know if it is possible at the moment but it seems that it should be simple enough to add for the auto voter platform. What it could mean is that even though there are less accounts in the trail each vote, the vote amount itself won't be adversely affected that much.
