For example, in St-Front-de-Pradoux in 2014, these were the second round results (source):
This was an unusual election in that Crouzille and Olivier each got 277 votes. French law requires that ties be broken by age. Crouzille's team had a higher average age and so won the tie-breaker.
Reading the Wikipedia page, I understand for towns with <1,500 pop. (such as this town), there are 15 Municipal Council seats.
Now my question: What is the formula/method used for divvying up the seats? Why did the 1st place (with 38.15% of the vote) get 11+2 (municipal/community council) seats, the 2nd-place (also exactly 38.15% of the vote) get 3+1, the 3rd-place (11.98%) got 1+0, and 4th-place (11.70%) got 0+0?
