is it even theoretically possible for that camera to have a config with no overlap at all? maybe 3 full up tilt with 1 down the hatch?

i am very happy to see IPVM testing Panasonic Cameras. I do like the over lap when using all four imagers in a 270 degree setup. I would like to see how it does with lens four turn straight down ans the other three adjusted to cover the 270 degrees of coverage and see how much over lap there is. The report and test is very good and covered every question I had about the camera. Best testing of cameras in real world period!

Update:
Added section explaining VMD performance. The Panasonic WV-X8570N does not include intrusion detection, we tested the performance of VMD and the camera alerted on the simplest of false alarm sources in the scene, such as blinking lights from switch ports.
