The test was a signal seeking trial in a third world country fostered by a company that has skated along the edge of bankruptcy for years. The only realistic purpose of this trial was to learn whether the company had a future, period. The results were good enough; PPHM is still here today and is now doing meaningful trials.
Criticizing those trials is looking at the rear view mirror; the real action can only be viewed through the windshield where we will see if PPHM continues to move forward or hits a brick wall.
