You don't get PREs at :01? I've never been able to catch anything (not just Zoltars) at one second cos everything keeps erroring out.
I think everyone is different. Different computers seem to get different PRE's (I say this not because I know all that much about computers, but I listen and I've been around a good while - ). People report all different abilities. For ME, some of it is related to time of day and mturk (which itself can be fickle). I remember around the Holiday when we got FLOODED with compare receipt Zings (filling up my queue nonstop for over an hour). I got NO PRE's running a 2 second panda and submitting quickly. OTOH, there are times when it is slow (not saying the cause is that - but saying I noticed it) and I run that 2 second panda and submitting when the queue FINALLY gets full............well, I can't get through it!
I think this situation is the same as everything with mturk: you have to play around with what might work for you, and once you get really comfortable with your system, you get screwed by amazon, who does what it does. So, for me, I watch very carefully all the time. I check and recheck my panda's and I adjust the refresh times, sometimes multiple times during the batch. It's a game and I need to earn enough money to survive
