"nice biggish road with no houses near road etc." but it was a 30 limit?
I was tempted to go off on singing, "Your once, twice, three times..................." but ill resist, we dont know if this last one was a camera van yet!
My advise would be, Where ever there are posted limits 30.40.50.......even 60, you really need to keep to those post to post. In fact its quite a discipline to do it. In between, i wouldnt say GLF, but ride the road!
If you rode the road outside of the posted limits to, dare i say an advanced standard, you would be glad of the posted limits to provide a little restbite. Im not saying your guard is dropped here, more that things are easier at a lower speed.
Before anyone goes off on one, i wouldnt even begin to try to try to lecture you. Those that understand me (difficult i know) will know where im coming from here.
If you do find yourself sitting on 9 points its got to be worth a try?
