The original question provides a good statistic, I think. Only 8 prefixes that were announced by more than 3 origin AS.
And the overall message is that only the (prefix holder|originating ASn[s]) can tell you if it is intended or not. Sadly, this is not a useful metric for a third-party to use to determine prefix annoucnement legitimacy. Perhaps an update to RPSL to allow for intentional multiple origins is overdue?
