TRS19 how to measure distance in Driver?

The "Display Custom HUD" session rule has been my primary way to measure distances to use in calculating average gradients over a length of multi segment track. Is there a session rule (for measuring distance in meters) that works in TRS19? The track profile at the bottom of the screen isn't accurate enough for rise/run calculations. Thanks

I finally discovered that if you put the cursor over the track profile at the bottom of the screen and zoom in to the maximum magnification, it will show the distance traveled against marks spaced at about 30-60 meters. I usually had the track profile zoomed out. Thanks.

Thanks for that, Dave. I was trying to figure that out myself because I also run zoomed out due to the amount of screen real estate the profile takes when zoomed in.
