I do not recall. I know at least some were sequential, but I do not know if they all were.
But, I would like to point out that nearly all PBW games (hosted by experienced players, at any rate) have events disabled because HWs can be blown up, or at least the severity set below catastrophic. This was not always the case, and in the early days of PBW most games had events enabled. So, enough PBW games had to have been ruined to see such a radical shift.
