It is difficult to know how this is determined but the original recipe did have a brew session but was not a snapshot or anything connected to the other two. There seems to be something going on here I can not explain. Perhaps someone else can? The entries mean nothing to me anyway but it may to someone who uses the information. This was in the Ripper Clone 2 recipe - which was a clone of Ripper clone 1 but nothing to do with either of the others listed.
