The very idea of looking at "elaborate" parts of the VMS is evoken by the assumption that the scribe was the originator of the script. If he ever was in need to "get used to the script" - that would mean that he was not familiar with it (e.g. was a mere copyist). In that case the writing, however elaborate, most probably would not betray the specifics of glyph construction, because the copyist understood no more in that than we do (and I think, even less).
Looking closer at f1r, I would agree now that it is not a good candidate indeed; but at the same time I would note that, although the writing is ambiguos, but, very strangely, only in part. What I mean is: look e.g. at line 1, vord 4. Is it ytaiin or ataiin? The first character is ambiguous. But, at the same time, there is a very clear y as early as in the very first vord of this line, and a very clear a is observed already in line 2, if not in the vord *taiin itself. This does not look as "getting accustomed". This sadly looks as having troubles in copying. Another option is that it was written just carelessly. That it is the first folio in the binding does not mean that it was written in the first place. A blank page might have been left for to be filled in later (like, to provide abstracts of chapters yet to be written).
