I agree with Fatdirk. I don't see why they didn't anticipate this being an issue. I can see at home it can be dialed in but from the two I played on location, you had to know the feed once it hit the last pop otherwise it was SDTM.
Wasn't fun, but that's also because the prison doors wouldn't open and the well walker was only registering direct hits maybe 25% of the time but that's a different kind of problem. I could only dream of the local op's only issue being a slight leveling issue.
