Sure, you are making great send and your analysis is very well founded... Have also kept my voting to my self most times since when the larger % of Whale would rather sell upvote and pass over your contents or vote with 1.0% just just to show they see you.
Those with large volume of SP hard ever vote anything worthy anymore except themselve and inner circle.

I move we voting be adjusted towards your suggestion.
Thanks for this enlightening post and lets pray the dev. See this and take action.
