You have 3200 SP. This means that if you vote with .0375% power, the vote will be logged in the blockchain but will have no impact on the reward pool. The practical impact of this change is that the tiny minority of extremely weak votes will have no impact on the rewards pool. There is no reason to take this into account when you are being active on the platform. All of the changes we do are always designed to ensure that the vast majority of users can just use the site intuitively. This change has no practical effect on anyone who isn't intentionally voting with insanely weak votes. Since the deduction of 1.2 SP per votes is applied across the board, everyone is effected equally, therefore there is no reason to adjust your behaviors, again assuming you aren't one of the people vote spamming.
