Is the election first past the post, or preferential?

If most candidates offer VOTER payouts the system of voting is important to know. If the system is 'first past the post', then VOTERS of most popular candidates will get a smaller payout for their VOTE.

E.g. assume results of election result something like this,

1. 6.50%
2. 5.85%
3. 4.95%
.
.
.
28. 1.10%
29. 0.95%
30. 0.50%

All 30 notaries still get ~1500 KMD per month, and obviously the best payout will be for notary 30. who divides his profit only for 0.5% of KMD, whereas position 1. shares his profit with a much bigger VOTER base of 6.50%.

Best payout will be for the bottom candidates who just scrape over the line, not the top guy with excess VOTES above a quota.

Preferential voting system would mean every candidate basically gets the similar sized VOTES.
