The problem with NP and updates is that once he says "This is happening" and "That is happening" and "We're having meetings" and then he goes dark, it is because NONE of those things happened and he set himself up for failure by telling us and then not telling us when things changed. THINGS DO CHANGE and I get that, we all do, but don't lead us to believe something, change it, and then not tell us in a timely manner. Say something or nothing, not in between.
He does NOT update us as often as you say, and while you are correct, he doesn't HAVE to update us, it is he who causes the SP to go down moreso than many here would like to believe. The shorts are the shorts, and I don't sweat them because they don't run trials or devise protocols. Results will speak louder than anything else.
