Deciding number of guests for short term rental

[Roxana Daneshjou]

I know based off of reading this website that airDNA is not always accurate with projecting revenue.  I am looking at a 3 bedroom, 2.5 bathroom place with a bonus room.  I was thinking of doing king beds in the two main bedrooms, and then a queen + a bunk bed in the bedroom downstairs, which is adjacent to the bonus room.  Then I was thinking of putting a sofa sleeper in the bonus room.  However, airDNA drops my projected revenue by 4k and occupancy by 10% if I increase the number of people to 10 from 8.  Is that just because the way the algorithm is designed?  Is it actually better to sleep fewer guests?
