"usage" is used to general

As we figured out in past, the strings should be much more specific or detailed and should say what it really do (remember the "Submit" > "Save" or "Submit" > "Create" discussion). It is difficult to translate strings like this:

Moved usage from raw to daily.

usage could be nearly ever usage. Usage of toilet, usage of water, etc. Be aware we will have a translation server for future that makes it more difficult to find out what is the background of this string and what it should mean.

This sounds much better for me:

Moved usage statistics from raw to daily.

There are several strings about this "usage"...
