Thanks one of my airplanes was in the hottest section

its a like per min thing
for example, a plane which got 5 likes in 15 minutes is an average 3min per like.
a plane which has 4 likes in 8 min doesn't have as many likes, but is hotter because it's average 2 min per like

2min per like is less than(better) than 3min per like.

It's so that good planes dont get lost in the newest section

Hope that helped
