Reweighted Range Voting (RRV) is a Proportional Representation (PR) voting method that feels like range voting described at http://www.rangevoting.org/RRV.html.

The example reweighting equation is [*weight* = 1/(1+*SUM*/*MAX*)] where *SUM* is the sum of the scores that ballot gives to the winners-so-far, while *MAX* is the maximum allowed score.

The noted general equation is [*weight* = *K* / (*K* + *SUM*/*MAX*)] where *K* is any positive constant.

An equivalent general equation is [*weight* = 1/(1+(1/*K*)**SUM*/*MAX*)] or [*weight* = 1/(1+*C***SUM*/*MAX*)] where *C* is any positive constant equal to 1/*K*.

As *C* decreases, the *weight* increases which tends to favor larger parties. When *C* is 0, RRV becomes Approval Voting (AV).

As *C* increases, the *weight* decreases which tends to favor smaller parties and independent candidates. As *C* approaches infinity, RRV becomes Single Non-Transferable Voting (SNTV).

Lets call C the Choice Constant.

In a PR vote with multiple winners, voters could select a numerical score from a range (e.g. 0 to 4) for each candidate. Additionally, they could select a numerical score from a range (e.g. **0** to 4) for the Choice Constant. The average of every voter score for Choice Constant would be used for reweighing all of their range votes.

Reweighted Range Voting with a Choice Constant would allow voters to have more control of the reweighing process.

Are there any improvements (or flaws) to this voting method?

Correction:

As *C* decreases, the *weight* increases which tends to favor larger parties. When *C* is 0, RRV becomes Approval Voting (AV).

As *C* increases, the *weight* decreases which tends to favor smaller parties and independent candidates. As *C* approaches infinity, RRV becomes Single Non-Transferable Voting (SNTV).

Should be:

As *C* decreases, the *weight* increases which tends to favor larger parties **and partisan majorities**. When *C* is 0, RRV becomes **Range** Voting (**R**V) **for PR with multiple non-transferable votes**.** With highly strategic voters, RRV becomes Approval Voting (AV) for PR.**

As *C* increases, the *weight* decreases which tends to favor smaller parties and independent candidates. As C approaches infinity, RRV becomes **RV** **for PR with only one vote**.** With highly strategic voters, RRV becomes Single Non-Transferable Voting (SNTV) for PR.**
