RC iMs hold times

I wasn't able to find the answer through a search of this forum (if its been posted all over the place and I just missed it because I'm dense....I apologize) , so I thought I'd ask:

 

In the F1 course it indicates a 30s time for the RC iM's.  

 

My question: In the iM's that use one limb at a time, does that mean 30s/arm, or 30s total (15s/arm)?

 

Thanks everyone!

30s each arm.

Great, thanks Murray.

No worries. I think there is a Foundation FAQ that's stickied that answers questions like this.
