Hit 200 laser scans on one site, learned my target spacing was off

Last month I wrapped up a 200 scan run on a parking garage retrofit in Austin. I kept getting gaps in the point cloud around the columns, so I checked my registration stats and saw 14% more error than my last job. Turns out I was setting targets every 30 feet but the columns were blocking line of sight, which pushed me to 18 feet spacing. That extra density cost me 2 extra days but saved a redo that would have burned $1,800 in crew time. Anyone else figure out their scan spacing the hard way after a big count milestone?
