the results are fairly close. I think you could make it a little more scientific by using the same tire. the apex valve stem might flow a little more. that could account for the slight advantage the VIAIR appeared to have. either way, I don't think you could go wrong with either setup.
I’m also thinking plywall load and vehicle weight would offer different resistance the compressors are fighting against. Really wish they would have done both tests on the same wheel/tire combo as well. Agree both are great companies and either would be a good choice.
