I'm not familiar with the 1Z polishes, I don't know how severe are your swirls, nor do I know if your pad was already primed with product, but from my experience with the polishes I use, my comments would be:
- overall ... NOT BAD IMO

- agree with previous post ... remove all jewelry first
- distribute the product in a thin ring around the pad or 3 or 4 equally spaced dots instead of 1 single blob
- vary the amount of product as the pad is primed ... i.e. use more the first few passes and less as the pad is saturated
- clean your pad with a brush after every panel or as needed
- don't work the polish that long because the polishes I use would have been fully broken down a little sooner than that. also, you don't want to dry buff.
- start with more pressure and lighten up to light pressure for the last pass or two
- feel the panel... it should be only SLIGHTLY warm, not really hot or very warm at all
- slow your arm speed down just a LITTLE ... at some points your moving the buffer at a pretty good rate, but at a few points it got just a little quick or "jiggy" .... overall not really bad though IMO.
I'm sure somebody else will chime in and give completely opposite advice
