This is likely an accumulated count. I say this because while attempting to understand the relay stats, I came to the conclusion that it was likely a count of disinct relays from it's entire database; an attempted global aggregate. A majority of the relays it counts no longer exist. So for zap sender to be an accumulated value, as opposed to a count within a time window is likely.
