locked Audio Frequency choice. #QSO_practices

Hi -

I have been using FT8 for 4 months on 40 & 20 meters and notice that signals bunch between 1 kHz and 2 to 2.5 kHz. Can someone explain to me (or point me at some good write-ups) as to why this happens? Is there some magic going on that I am missing, or is it just herd instinct? I generally try to use 800-950 Hz, and get reasonable results with a QRP rig and compromise antenna. Thanks in advance, 73.
