Hasn't there only been 2 examples of extremely minor guidance revision (relating to the same period)? I do not believe the revision represents systemic issues in the company/by management. I've been following these guys loosely for a few years and my understanding is that management are very transparent about their strategy/operations etc overall. Could you elaborate on people's concerns re their credibility? Admittedly I'm much more across the fundamentals than I am the specifics of management & how they are perceived. I had drawn my above understanding prior to buying ( so I don't think I was being biased when i concluded, although I may have missed something)
