Well, it's your idea. So, I suppose it falls on you to try and talk the whales into witholding upvotes for a period of time as an experiment. I would advise that if you manage to pull this off, you make it between 36-48 hours. As with payout lasting longer than 24 hours most of the time, I feel to get some fruitful results we would need to extend the time to account for that.
I hope to see it happen.
There is some interest in the community for the idea, even some whales seem to be interested by it so we will see how it pans out. There are still a few issues that needs to be addressed in the proposal to make sure its not gameable. @timcliff also came up with some interesting ideas
