Code review comment for lp:~julian-edwards/gwacl/augment-rolesizes

Thanks for integrating this. It may seem strange that I used thousandths of US dollars in my branch, but that's also what Juju's EC2 provider does. EC2's pricing structure makes use of the extra precision, and Microsoft may find they'll want to tweak their pricing more.

I think it's still worth saying in so many words that we make no guarantees with these cost indications and that we'll happily let them go out of date if no updates are required for our purposes. Otherwise, your statement that the information is correct (do we even really know that?) as of a given date may reasonably be construed as a promise to keep the list updated.
