This is a great question! All of the votes from here on out (assuming the hf has no problems) will be under HF21 rules. If I understand it correctly, it will be difficult for actifit to continue voting the way they are because it will take a much larger vote to get to the same vote value because of the nonlinearity at the bottom of the curve. I will be interested to see how this is handled. One option would be to up the minimum afit token needed to cash them in so they can use larger votes to reach that target. For instance, instead of voting on a person many times when exchanging 20 afit, they could up it to 200 afit tokens and vote on them once a week or something like that.
