I think, based on looking at maps - because when I ran one of those technical courses my Q rate wasn't stellar, either - that neither the dog's path, nor the skills required, are even remotely 'new' for NADAC - and I don't mean going back 10 years to points there are teeters on the course, either. I've been running for all of about three years in trials and I've seen all those lines, and all of those handling challenges before.
The flow is still there for the dog - it just requires more active handling, more crosses, and really good timing. Those things are not easy. The courses are not easy. But I just keep not seeing anything there that is reminiscent of anything but NADAC, or that truly requires new skills - either for handler or dog. Less forgiving of mistakes in using those skills, some new application of skills, but I don't see anything there that's worth freaking out or stressing about.
Then again I've pretty well decided that short of a teeter on the course - or some other obstacle I have not trained at all - I'm just not stressing out or freaking out about agility at all. I'm not saying this is good, but I just refuse.
