"Using something similar to the calculated CSI on SteemWorld as a factor, so that the voted rshares would be multiplied by it prior to subtracting them from the pool and adding them to the active votes."

Sorry but I think that it's not a good idea to use CSI on SteemWorld as in my opinion CSI isn't a reliable factor.

If I see that an account with 100% self-voting (no vote to anybody else just vote for the own account) has an CSI from 0.0 but other accounts has negative CSI, f.e. my account in the moment, than Steemworld consider it as better to vote 100% only your own account instead of voting for others.

How this can be a reliable factor ?
