Had another go today with version "C"
So tried the screen flip, and wore the watch on the inside of my left wrist. The theory being you can see the screen going down the run and have good reception. I couldn't see the screen with my polaroid sunnies, because the angle was just too acute. Also I had to twist my arm to be able to read the display even stationary, and all the buttons are upside down. I felt much more comfortable with the watch when I un-flipped the screen.
I think everybody will have to try this for them selves, without Polaroids on it's probably more useful.
Looking at the data, there's no noticeable difference in the accuracy variations, still very good one way OK the other, except with the flipped screen the good side is now the underhand grip.
The 5xNs average has still got a bug, it keeps loosing numbers, I think I only once saw the display with all 5 spaces filled, most of the time there were only 2 or 3 results there. At end of session the watch display said 11.49kts, the average of only two 28s, when GPSResults says my 5x10 is 33.025
The speed genie display on mine now shows, distance -- @500 & 500m --- max spd & 10s
TOP RSLT numbers, max 34.91, @ 22.36, 100m 34.23, 250m 33.42, 500m 31.00
GPSResults says @ 22.390, 100m 34.23, 250m 33.423, 500m 31.008, so apart from the 5X10 there's an exact match to 2 decimal places.
