How "consistently for" is worked out

The MP's votes count towards a weighted average where the most important votes get 50 points, less important votes get 10 points, and less important votes for which the MP was absent get 2 points. In important votes the MP gets awarded the full 50 points for voting the same as the policy, 0 points for voting against the policy, and 25 points for not voting. In less important votes, the MP gets 10 points for voting with the policy, 0 points for voting against, and 1 (out of 2) if absent.

Then, the number gets converted to a simple english language phrase based on the range of values it's within.

No of votes Points Out of
Most important votes (50 points)

MP voted against policy 0 0 0
MP absent 0 0 0
Less important votes (10 points)

Less important absentees (2 points)      
MP absent* 1 1 2
Total: 31 32

*Pressure of other work means MPs or Senators are not always available to vote – it does not always indicate they have abstained. Therefore, being absent on a less important vote makes a disproportionatly small difference.

Agreement score = MP's points / total points = 31 / 32 = 97%.
