I was reviewing my recent onboard and noticed that sometimes speed delta is displayed as +0 with green background,
or -0 with red background. Given that GPS speed isn't super precise to begin with, perhaps when the absolute speed
delta is <1, it should just be displayed as 0 with gray background?
It's the easiest to see at 1:02 in this video. As a reminder, you can use ,/. to review frame by frame.
