User blog comment:BonesMcGee/Brainstorm: Potential savings in using the hurry hatch trick/@comment-5216601-20120911142159

after several days (4-5) trying (no longer than 20-30 minutes a day)

to get a rare dino from random egg, I finally got a new one:

The Mesohippus !!!,

which I was still missing, super

so that will make 27/30 soon.

Next time I will try to count the nr of attempts.

(but rough guess is that this last one took me somewhere between 100-150 attempts at least)
