@robev I don't think anyone thinks chirik yud is a tenuah ketana and also holds of the 'normal' kimchian rules of tenua gedola and ketana viz-a-viz shva na. It's probably simplest to think of the position as tenuot are all equal and aren't split into big and small.
@robev Long and short vowels are grammar terms introduced by R' Kimchi. On the other hand, the Masoretes were not interested in rules, but in describing the tradition they had received. They are different approaches, but both are valid and have arguments supporting each of them.
@robev Because both Pinchas and Pinechas are valid options, and indeed there are current traditions preferring either of them. I'm fine with both as long as they are consistent.
