Experiment: how would you transliterate the following glyphs?

[pfeaster]

What it the tail of EVA-n but an empty flourish though? Is there any case where it adds information apart from "this is the last minim"?

Edit: well I guess looking at Patrick's example, it could indeed be seen as one variation that just happens to be the most common one.

It's true that this raises the question of why certain combinations of [i] or [e] with particular flourishes should be so much more common than others.  Why is [n] so common, but [b] so rare?  Why is [d] so common, but [j] so rare?  Why are [y] and [l], or [s] and [r], more evenly balanced?
