The activity dates as I understand them are supposed to be when the
shower is detectable by visual means. That's not to say that there
aren't Perseid meteors outside of those dates. July 10/11 is plausible.
July 2nd, I'm doubtful. That early the radiant position isn't well
defined. It's at best an extrapolation, and some observers (not Jure I
hasn't to add) ignore radiant motion.
