I laugh at the term "bedding area", nevermind the unicorn that is a "buck bed". Bedding happens just about everywhere around here and while there may be enough consistency to call an area of high use a bedding area, those areas still aren't a given. I've found 2 beds in my 20+ years that I was certain were buck beds and both were found late summer when they're super predictable. It's just not a tactic that works around here.
That said, I killed my first wall hanger with this technique after finding an area of condensed sign so obvious, there was no missing the fact a buck was spending most of his time there. Because the area had been brushhogged recently, it narrowed down the options enough for a wind bump and I killed him standing up from his bed. Still the "craziest" idea I've ever had that work to perfection.
