The guy who did a lot of work on EVR-CP a couple of years ago disappeared leaving very little documentation, but yes, I believe it's normal. It certainly has nothign to do with vsync. The flip side to that is you cannot use it, like EVR Sync to help you find the right vsync target. Also the stats do not pick up "sync glitches", like EVR Sync, so you can have judder that is never reported in its stats.
