We’re taught from our very first lesson about scanning for other gliders, that maintaining a scan is super important when studying clouds, or the climb rate of turning gliders ahead. Having your head buried high into a cloud for 5-10 seconds straight, studying the optimum climb point or path is far too long.
Why? Everyone else is doing the same, so have a good look, then start your scanning habits again, because others are attracted to the same thing you are, and could be similarly distracted! You have a responsibility following, or being in the vicinity of another glider to fly in a way that will not endanger either of your lives.
