Without some actual notes on which programmes have been affected (and how long for) that would be very difficult to calculate.
However, giving it a go, I would guess there's been getting on towards 15000 hours of programming produced from NBH since it opened. Putting Harshy's 85% figure into that would indicate over 2000 programmes affected by automation issues.
Personally, I've not seen any issues in the last few months (apart from the hungover trundlecam at Christmas - which sounded mechanical rather than automation based) when I've been watching. I don't know if that's representative or if I've just been lucky.
Who was it that said that it takes 20 years to build a good reputation although just 5 minutes to wreck it?
The point is that there are "issues" some of which are headed off by the directors. Sometimes things don't work although those things are not always obvious to a viewer. Mosart works best for structured programmes like the five, six and ten although is slow and clunky for any breaking news scenario.
Of course, I'll admit I've seen a few on-screen errors live since the move, as I'm one of us that looks for them.
But what I've mainly seen is far more camera angles being used (esp the national bulletins, the Ten being the one I watch nightly), some really nice moving tracking shots that you would never have seen in TVC's bulletins and overall, I think, a really polished, professional output.
If I'm up early and catch the World Today, there's also a greater variety of shots used and some really nice intros/outros and headline/report sequences complete with crisp, clear stings and perfectly timed transitions and effects. That said, I'm not convinced Newsday works with the split screen setup but overall the quality of the output, to me, seems really high - and in most cases, almost perfection.
