I'm still curious about what dbs you do get when have a good loud session. I've quoted here before that the Foo's CD clocks 110+ at 85 on the M scale. That surprised me and have to say I don't do it much now as a result.
This would only be possible if the listener calibrated at 7+dB above reference levels.

87 on the Meridian scale equates to 105dB for 0dB fs (a full scale digital signal)

You are talking about 7dB above that (5 for the 105-110dB difference, plus for the 85-87 difference).

This is the beauty of having a reference std. You are calibrating a tone of known level to a known SPL. Therefore, you know what the other levels will be as well.
