The thing you may not be understanding is the fact that it isn't trying to grab each of those hits every time it cycles... it tries one and then the next then the next and so on. So there can be quite a significant gap of time between attempts on any single panda when you are running so many. You would more than likely have better luck reducing the number of pandas you are running so that each one is actuated more frequently giving you a higher chance to catch it.
I do understand that
I can see it upping the count on each hit one by one.
All I was trying to say (and failed) is that I don't know that is as much as 1 second between tries, as I often see the ms below 1000. --edit--though I guess it could often be rounded to 1 second as it's pretty close to that anyway, unless in HAM mode now that I just played with it all.
Max pandas I ever run is 8, most often less, and I'm not all that disappointed with their return rate. I also don't get many PREs unless I'm really doing batch work. That, more than anything, seems to up my PRE count. If I'm in the zone on 5s after a bit I need to walk away and let Amazon reset whatever the frick it is using to determine PREs so I can go back to zoning on them again with fewer PREs.
