To be honest, I'd suggest just letting all 5 slip through at this point, rather than continually drawing out an early round with tiebreakers.
"drawing out" doesn't really matter as normal contests still continue in contrast to the older LOTY votings -- so it doesn't hold anything back like in recent years.
Also if we got a very big tie, then one group gets too many survivors, making the survival rate unfair in comparison to the other groups. Here it's just a small shift, but I want to be consistant and handle the groups equally. If we get a full on tie between the remaining tiebreaker candidates I will resort to letting them all through.
I want to keep that survival ratio as fair as possible. I would take a few tiebreaker rounds and a longer voting phase over unfair survival rates.
For next year's LOTY I already plan to further limit the nominations a person gets, due to the exponential increase in nominations we got this year. This should counteract the length for the next year.
