How many hours did it take you to get to Auraxium medal(s)?

Thought this would be something interesting. I know there's probably a lot of idle time involved, but stats are fun.

For me:

21 hours to get Auraxium for Rocket Pods
17 hours to get Auraxium with the Carv (probably about 1 or 2 hours idle at most, I only started using it at the beginning of double EXP and was mostly focused the whole time)

That's all I have so far since i've tried just about every weapon and swap often.
