Looks good but still the research between these data and the standard terms, already used in numismatic literature is absent.
It is well known term 'so many o'clock'. So there should be connections, that these many o'clock mean this coin (type of coin) with a photo as optimal. Some variants with other numbers o'clock described in literature are absent among the photos.
Most probably during the preparation of the data presented here, to the changes request it is worth to think:

https://static-numista.com/forum/images/59e476979edee.jpg and next the term 'normal' is not correct. It is worth to check what specialists mean, when they say 6 o'clock for coins which changed coin to medal alignment. And the term 'normal' is not good: just numbering is better. There is large chance that 'normal' and 'variant 1' is the same.
Term "normal" means that there is something peculiar. But it is difficult to name the edge variant 2.4 as something special when the whole year mintage most probably was the same and other then the term 'normal'. It is still normal, yes, to that particular year.
