I wish it covered (so to speak) aluminum foil more thoroughly.

In particular, foil is cheap, so rolling up in several layers (3? 5? 10?) and twisting the ends cracker-style ought to be more reliable and practical than trying to do it with one layer and fiddly seams. A suggested minimum number of layers and number of twists would be useful.

I wish it had covered practical tests more thoroughly. As in: did the phone communication effectively drop dead once in the cages which measure well? Looks very likely based on those attenuation numbers, but still: 'question everything' is usually the way to go in test&measurement.
