So I’ve found that a few seconds after popping a scent the first dino spawns from it. Then the next dinos all spawn about every 2 minutes. This means with the 5 minute scent you get 3 spawns but the 20 minute scent you get 9. I’d rather pop four 5 minute scents and get 12 spawns instead of 9.
Is there some other benefit to using the 20 minute scent?
