I did it early on but not right away. Had 2 glitch but you just save and quit to dashboard and the glitched ones will be standing up again. i just made note of the ones that didn't show a counter. You can argue about which ones glitch (like half the guide on TA) til you are blue in the face but it's random. And the maps are easy to read even if you already hit about half of the gates because part of the gate usually respawns later and it's pretty obvious which areas a gate can be found in.
