Power nap and iCloud syncing

I may have the opportunity to start using a Mac mini for my day to day work and a MacBook Pro for travel often without or very slow wifi.

Has anyone figured out if the intermediate sync data that DT uses for iCloud syncing, is sync’d during a macbook’s power nap?

My concern is that I will make a lot of changes while working on the Mac mini, but will then have long sync times once I open the laptop, or worse, forget to sync before leaving and have to rely on a crappy hotspot to sync. I’m hoping that the power nap feature on the laptops will grab the iCloud sync data and at least have it local on the machine.

iCloud should upload changes in the background (also during a power nap) but databases don’t download changes during a power nap.
