Some useful points there Ian, in the same vein as Martin.
I think at the moment I am moving into your Category 2 from Category 3 - albeit a little like the hokey cokey - and it is fair to say that, as in the round that prompted the OP, that my first tee nerves are decreasing as my skill level increases.
The other side of this is that it is a bit like a virtuous circle, the less nervous you are the more likely it is that you'll hit a decent shot, which reduces your nerves....
At the moment I'm getting towards your "8 out 10 rule" across most of my game - or at least I now take my "range game" to the course for most shots for most of the time.
The exception* is the driver and luckily, because I think its easier for me at least to solve than a mental issue, the problem there is technical; I have a couple of swing flaws that I am working on - so at least one of the people at the range hitting his driver is doing it for a valid reason
.
Thanks to all for the advice on this one.

* Actually to be fair I do take my range game to the course with the driver its just that its not very good
- well awful in fact, hence the work I'm doing at the moment.
