@Peregrina - (like NI) because we have multi-seat wards, there's a quota for the first round, which may or may not be reached by a candidate(s) before it goes to the reallocation for subsequent rounds.
The difference with NI is that our voting is counted on computers (they look like printers), so after the initial validation, it's dead quick as the computer does all the reallocating for the various rounds until it gets to "last man standing"
Hence why we could report our results on Friday
