Interesting from a SCA perspective and you did good.
Guards you should were Plow, Italian variation is Posta di Breve (Short Point) and you also showed Vadi's Posta Longa con la Spada Curta (Short End Long Guard). Nebenhut or Posta Coda di Longa (Long Tail). Ochs, Posta di Finestra (Window Guard), Vadi's Posta di Finestra Vera (True Window Guard).
The Italian system also seems to favor a thrust more which is fine but I don’t consider thrusts to have as much duel ending probabilities as a solid cut does except of course with harnischfechten where the thrust is king
Which is true to a degree, there are many plays that Fiore will use a thrust to set for a technique ending in a cut and vice versa.
Heh, I find that amusing, since to me, the German system comes off as rather simple in concept. It's also delightfully medieval, in the sense that if a bunch of things are mostly similar, they must be the same thing, so they're lumped together. 
One thing that's cool about the German manuscripts too, is that for the most part, they're not always written with the approach of "this is the way it must be done", but rather, "here's something that works, try this"
I agree.
