Corner base trap- to the ceiling?

My room is on the smaller side and I have a floor to ceiling bass trap behind my speakers in a corner setup. 

If you are serious about it, all the way to the ceiling. Upper corners are just as important as lower corners.

I guess my question is this: If you take out your feelings about AF, he is presenting a solution that is backed up by the numbers. Mathematically, you would want to know how much pressure you have and at each frequency. Then you would want to apply the solution that is designed to fix the issues (unwanted high pressure frequencies.) 

If there is another solution out there (corner bass traps) that can also be used, where is the objective data and room testing process that dictates proper performance in mitigating the unwanted frequencies?

Given how long are bass frequency waves, the pressure of the soundwave is highest at a boundary because the positive pressure of the wave moving toward the wall meets the positive pressure of the wave reflected back from the wall (the incoming and reflected back portion of the wave is still more or less in phase).  A corner has two such boundaries making it the best place to put devices.  Hence, a corner is the best location for a device trying to attenuate lower frequencies, but, people do tend to expect greater results than they deliver.

But, even quite large diameter traps are not that effective at very low frequencies, so that they don't do much below 60 hz or so.  Still, they do tend to smooth out bass response to some degree.  The ASC tube traps have one side that is designed to reflect and scatter higher frequencies (act as diffusor), and one can thereby orient the traps to either absorb and dissipate higher frequencies or reflect that energy back into the room.  You can experiment to determine which is better for your setup.
