Yeah, I'm pretty sure I defined this before, but if they had 40 contestants it could be like this:
Auditions - 4 weeks, 10 chair turns per episode for 40 chair turns.
Battles: 3 weeks, 6/7 per episode (2 might have to be shortclipped). 28 contestants survive the battles eliminating 12, but the 4 saved contestants go straight to playoffs for a wildcard vote. 24 contestants going into KOs.
KOs: 2 weeks, 6 KOs per episode for 12 total. 8 contestants are eliminated for a top 16.
Playoffs: Assumed live (meaning this makes 4 weeks of lives instead of 3) - If Monday only then the top 13 would be decided in one night (live voting), otherwise the top 16 would perform Monday and results Tuesday (I remember S16 initially had 6 weeks of Monday only and not 4 like we got). Top 2 votes for each team advance, coach saves one more. The saved contestants from the battles participate in a wild card that works exactly like it did in S17.
Top 13->Top 8->Top 4
Seems semi reasonable ¯\_(ツ)_/¯
