If you were in division V you would be promoting for certain! You can work it out from that great information from atabakin. Just look at every division IV for the records of teams that wont win their league. The best 8 records will promote anyway. Are you one of them? Easy!
Doesn't it not entirely work this way though? My understanding is that if the team in his conference wins the finals (and they won the 1st game), the finalist from the other conference in his league is in line for bot promotion before he is, even if his team has the better regular season record.
So, it's possible that in addition to anybody who has a better record, he could also be behind any teams that made the finals in other leagues but then didn't win. Which obviously would prevent him from bot-promoting.
I'm not going to say I know this is right for sure, maybe someone can correct me, but I'm pretty sure that is how it works.
