Subject: BlaumRoth with w=7 : what are the consequences ?

Hi Kevin,
When implementing the plugin for Ceph, the check for isprime(w+1) was not added and w=7 was made the default for the BlaumRoth technique. As a result all content encoded with the BlaumRoth technique have used this parameter. I do not know what the consequences are. It does not crash and from what I've tried content can be encoded/decoded/repaired fine. But maybe I was lucky ?
Your expert opinion on the consequence of chosing w=7 would be greatly appreciated :-)
Cheers
