Have you spoken to Davis lately? I have. The knowledge of some is very lacking and may have been the issue in the e-newsletter.
I wouldn't speak to front-line support at all normally, partly because it tends to be the wrong timezone for calls from the office here, but more because I've got access to dealer support deeper inside Davis if there's some uncommon issue that I can't answer directly. (Actually, as it happens, there was one today - what's the spec of VP2 wireless consoles sold in China? EU seems to be the slightly bizarre but accurate answer.)
But I agree, Davis front-line support sometimes does not seem to be as knowledgeable as it could be, indeed as I admit myself on here from time to time. What does irk me in particular is the seeming tendency to make up an answer rather than to say 'I don't know for sure but I'll find out and get back to you'. Some might say that it's the enthusiasm of youth, but I'd probably use different words. But from what I know this newsletter is not written by anyone in front-line support hence my rather different view of it.
