More on the latest Google Earth tweak
Again very well stated, Bob. What occurs to me now is that many of us have been noticing that even when you get great closeup views, Google Earth has been stating course length a bit on the low side. Maybe because distance has hitherto been calculated for mean sea level? Will the "ground level" measurements be a whole lot closer to our (Jones-Riegel counter) results?
About very small start-finish separation: I like that, rounding to 0.1%. Or we could say "<0.1%".
