I think you are right Jako. He can't handle the technology.
He just comes across as having no knowledge about the software he is using and then tends to stuff around doing things like working out how to produce a trend line for example.
By the time he gets organised Gavin hits him with something from left field and you have to then endure David trying to find his way around the software again.
It is easier to just wait for his book to come out but I am sure there is something about the Weis waves that will be helpful.
