About Americas Championship Points

Okay so now that 100T has more championship points than SEN and since SEN isn’t guaranteed anymore, I have this confusion - Suppose 100T qualified for Champs via Split 2 playoffs and not Championship points so we would still need to pick one team via championship points so will SEN qualify regardless because 100T already qualified by being top 3 and SEN would most likely be #2 in championship points? Also let’s say SEN and 100T both qualifies via playoffs so will another team who’s #3 in championship points ranking be qualified as the 4th spot in champs?

whoever has the highest championship points out of teams who are not yet qualified will get that spot

split 2 points matter too, standings could be different than now, so sen needs to farm wins
