I had a problem with smartbeaconing pegging me twice on a long slow curve on 
a main highway.  The solution was not the minimum interval, but the "fast 
speed" setting.  The only place you want smart beaconing corner pegger to 
mark a corner is when you turn off the expressway, or main street onto a 
side street.  The fastest I would _ever_ make a 90 degree turn off a road 
would be at 20mph.  So set your fast speed setting to just over that, say at 
30mph (50km).  That way if you are travelling down a winding mountain road, 
you are surely going to go faster than 50km/h, and the normal 1 position / 
mile function will report your positions.  If you slow to make a turn off 
the road the corner pegger will get your new position out.

I think most people think of the fast speed setting as expressway speeds (ie 
60mph).... it should be treated as "any speed just faster than I'd want to 
turn off the road at".... in my case, in the 20 to 30mph range.
