Bob,
I've used 3 different room measurement systems. By far, the Velodyne SMS-1 yields the best, most consistent, and to my ear (although I'm comfortable making such judgements only from above 60ish hz) most accurate results. Many people would agree that 5db or so in rise is useful in the deepest bass. "Not quite" ruler flat means a gentle rise below 50hz to app +2 or 3db at 25 hz. With organ music (my test for this region), the gentler rise "feels" better TO ME than what you suggest at my normal listening level. Again, I'd be the first to acknowledge that others might side with you on this one.
