This looks good and since there are really no advantages to CRE there's no need for anything fancy to allow the client to use both CRE and this new measure. The client (i.e. the view rating dialogue box) might as well just be changed to use this new measure exclusively.
For display purposes, I'd recommend displaying a user with too high of a rating deviation as "provisional" or something similar, rather than showing a 0.
