More an issue for a single momentary reading, or something like the peak speed value, not so much if you observe the same number for a bit.
That's why I usually throw out abnormally high numbers.
Today i got out in 15kts with crew for once! Mounted my phone and watched the gps reading and we were able to hit 6.3kts upwind for about a minute and 9.8 on a broad reach. Did this with my old original sail so I wonder what difference it would have been with my newer sail. The OG sail is about 10% smaller.
