W1=W0+100\left( 1-\frac{e}{M}\right)

(the formula shown above is temporary and may be subject to change)

By repeating this process several times, you can get as many winners as you like, which will be those removed in point 5.

~~The~~ ~~first~~ ~~two~~ ~~unmet~~ ~~criteria~~ ~~are~~ ~~derived~~ ~~mainly from the fact that~~ DSV wants to ~~ensure~~ the victory of the candidate who wins all ~~the head~~-to-head ~~(when it exists)~~.

[[Consistency criterion|Consistency]] is not satisfied because [[Distributed Score Voting|DSV]] wants to guarantee the victory of the candidate who wins in all heads-to-head matches.

~~The~~ ~~last~~ ~~two~~ ~~unmet~~ ~~criteria~~ ~~can~~ ~~instead~~ generate tactical votes, described below.

[[Later-no-help criterion|Later-no-Help]] isn't satisfied because [[Distributed Score Voting|DSV]] wants to guarantee the defeat of candidates who aren't in the Smith set. This can generate tactical votes, described below.
