Personally I start off by tightening them gently by hand with a normal allen key and I use something more like a 1-2-1-2-1-2-1 sequence to ensure that they are tightened absolutely evenly.
I only get the torque wrench out once this procedure has been completed (and even then I might torque them in two stages rather than giving them full torque in one go).
Also, using this procedure, I then reckon its ok to torque them to the lowest end of the recommended range.

Agree entirely.
I had some aftermarket PVM radial mounts fitted to 916 forks and they broke even using the recommended torque settings so be careful (but please leave the spindle nut in place, nice and tight).
Broke during a ride, though I didn't notice until I was home, they were very thin/lightweight metal though presumably for race application?
PVM's attitude was very unsympathetic BTW - "we've got one pair left we can sell you at an extortionate price" rather than addressing it in any way which was disappointing as I thought them to be better than that...
