Essentially. For me it be worth it if it gave you lost knowledge on say how this school of swordsmanship did things, or this one did that as a way to revive stuff that in HEMA we're kind of Frankensteining together from old surviving manuals and sparring.
But I think the way your describing it there would be no way to separate things back out so you'd really lose out on the historical revival angle that interests me.
Ah well, I'd just choose Economic and be a rich guy.
