Always have and will continue to do so. They are 100% effective first lap, 90% second lap......... and become less relevant as the track deterioates. A good navi will update them lap by lap. Gives them something to do.
I have not used pace notes in Off Road, however I have used them in Rallys, if done well they are very good, as you get very confidence in the navs calls. A good pace noter has a call for each bend in the road and a suggested speed as well as corner type eg tightens on exit or opens on exit.
im finding it takes a few laps to remember the track , even than im still getting caught out on the odd occasion is there a standard note calling or is it something you come up with ?

were we're goin we dont need roads.
it's not the speed of life that scares me, it's the sudden stop at the end ,
We have tried a number of systems. We grade everything 1(dont lift) to 5(hit brakes hard) and then call it. 1 right (flat out right), 3 bump (lift and light brake for bump. 5 rock (hit the brakes hard before you get there). As a driver you hear a 1 and you keep going, a two you push a little, a 3 and you dont brake or accelerate, a 4 and you touch the brake, 5 and you bury the brake in the firewall. (the way you drive fez you probably only need 1 and 5) We then extend that the next step by adding stuff like 2 left stay in or linking them 2left stay in into 3 right rock on outside. All our numbers are relative to the speed we are doing so a 4 bump would not be a 4 bump if you slowed way before as you could feasably be accelarating at it so it becomes a 1 bump. As a consequence the navi sometimes modifies as the pacenoting s done at reccy speed so it takes some practice to get them correct right out of the box. It also takes serious concentration on the navis part as you have to trust them fully. I distinctly remember one Mogumber sliding sideways on two wheels through a creek crossing while asking for the third time what is coming up as i was travelling at serious speed around a blind corner - so watch out. In our class 5 our first lap was always the fastest and we reduced our speed during the event as the track deteriorated. Our class competitors were slower to start with and seemed to get faster as they learnt the track.
