I am certainly interested in how they compare, but as far as flexural strength is concerned, my testing equipment, although it follows the recommended 4 point test standard, employs a torque rather than hydraulic load. This allows me to satisfy myself, but wouldn't stand up to certified testing standards. I could design permeability tests, but probably won't bother, I'd expect little difference.
