SIP simplified voting acceptance formula suggestion

[oron...@gmail.com]

Hi,

I watched the October SIP meeting and I have a simplified formula suggestion:

P = Number of votes in favor
N = Number of votes opposed
T = Minimum for acceptance
(People can abstain)

So to accept the proposal the following formula must be true:

P - N > T

T is set as the required filter by the committee.
Suggestion: select T as half of the committee members.
Note: T can also be a constant

The logic behind this is that enough people should care to vote in favor, while not enough people care to vote against.


Example:
Committee of 8, so T = 4

• Proposal A: 4 persons in favor, none against, the rest have no opinion and abstain. The proposal is rejected.
• Proposal B: 5 persons in favor, none against, the rest have no opinion and abstain. The proposal is accepted.
• Proposal C: 5 persons in favor, 1 against, the rest have no opinion and abstain. The proposal is rejected.

Rounding when calculating T:
Considering that the condition is `>` in the formula, it is suggested that if indeed T is selected as half the members, then the number will be rounded down.
E.g: Number of committee members is 9, then T will be 4. So if 5 persons in favor with none against will accept the proposal.


Regards,

How is that more simple than P/N > T (which IIUC it is currently)?

Anyway if a meeting would 1000 voters or 2 the same T would not make sense in your formula, so your formula doesn't suffice.

I missed your suggestion of P-N > (P+N)/2 (or is it P-N > (P+N+A)/2 where A is abstainers?)

What is the advantage of that over P/N>T (it's not simpler btw)?

Notice my definitions of P and N. N is NOT the number of voters or committee members.
Before the October meeting the formula was:

P/Q > 70%, where Q is number of people in the committee quorum (not committee members).

See this discussion why this is bad.

The October meeting changed several things (if I understood correctly):

• The voting will be among all committee members, even those who did not attend the meeting.
• They allowed people to abstain
• The formula was changed to two conditions:
• (N + P)/M > 50%, where M is the total number of committee members
  
• P/M >= 2/3

The second formula is P/(P+N) >= 2/3
