Wish I could remember exactly what the cost to quickly open the different incubators was. I want to say it was something like 84 for an 8-hour and 9 for a 3-hour.
Let’s just use those numbers…
To get to a 15-min incubator, you have to open three 3-hour and one 8-hour. That’s 3x9 + 84 = 111. Now let’s discount it a bit for the speed up videos and just round it off to 100.
So every 100 hard cash spent speeding up incubators, you can open a 15-min incubator and get 3 stat boosts.
Spend 500 and get 3x5 = 15 stat boosts. Hmmm, that doesn’t sound so good.
Oh, wait, every fifth time through you get a 12-hour or 24-hour that costs even more.
That doesn’t sound so appealing.
