Blumenkraft,
Concerning the residue of the upcoming calving: parts linked to the extensions R1, R2, and R3, parts that will surely calve (either very quickly: last piece of R1, or a little further for the others), but that cannot be considered as new calving and taking into account that everybody knows them, I propose to prefix it: exR1, exR2 and exR3. In clear one considers it as a regularization of the current calving, but certainly not a new calving.
NB: the case of R3 is particular, it is not clear if he has calved in its entirety or if there is an extension pending (to be followed).
I attach two zooms of exR1 and exR2
From two marginal rifts that opened very quickly, but that stopped after R3 opened, and that are surely to be followed, we can indeed name them mR1 and mR2.
It will be renamed R1, R2 if and when it will be the case.
For the moment I will avoid creating other names; indeed it is necessary to limit the naming only to the very next discussed cases and to use it sparingly to avoid any complication, possibility of confusion and even usefulness (if you have many names you don't know what they mean anymore).
Baking,
I'm all for "The point."
Stephan,
I would not tell much about Cork2, it seems structurally very weak and there is already a fracture at the base, if you blow it goes away
