Corner base trap- to the ceiling?

I wouldn't place too much faith in Acoustic Fields. He is promoting his own solutions, and flies pretty far from a lot of the accepted acoustics theories with little in the way of real data. Having said that  corners are the most effective place to treat low frequency room modes, but it can take a lot of absorption to address modes below 100 Hz. If possible it is best to identify the modes you need to address, and use a combination of speaker placement, listener position, and room treatment to provide the smoothest possible low frequency response.

Multiple (2,3,4) subs can be effective in smoothing out response as well.

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?
