Dude. Look at my location. Now look at his. I never met the guy in person, I just talked to him from time to time on ASC, and read what he wrote.
Still, I will personally vouch for the guy as being a stand-up guy.
You had bad comms. That needs to be addressed, and creating a thread about the subject is still within reason.
This being said, don't assume people posting here are friends defending him.
I read your whole post as I did this thread. 8 hours total time might be a reasonable time quote, but there might be other issues such as time for part delivery, other guns in queue before you, personal issues or anything else.
Your fears have been publicly vented, give the guy a chance to get back to you before going gun-ho on the rest of us.
