OK, so everything you said might be true (I have no in-era evidence to the contrary) but nothing about my parses on P99 suggests that it's been implemented that way.

Misses are clearly checked before any defensive skills, and that's my main concern. Riposte also appears to be checked before block, which according to the sources I've found is also incorrect.

Speaking more directly to your reply, I clearly remember being able to turn on counterattack on my rogue on live and dishing out ripostes without limits to pretty much everything that happened to be attacking me, though I do remember flurry being an exception (those damn flurry drakes in NToV were the lesson in this case). There are also a lot of people in the various threads I looked at who talk about using rip discs to "blow up" train pulls to AA grind (obviously post-classic era, but like I said, in-era evidence is not readily available). I remember doing this as well during my tenure, all of which suggests there was not some sort of limit on successful riposte checks over any given period of time.

Finally, even if there is some limit on normal combat ripostes, disciplines have always broken the normal combat mechanics in various ways.
