Know more about circle mode

Hello everyone I want to know more about circle mode , i know there is exist circle rate but i don’t have PC and laptop so all time I’m pushing in mobile app QGC. There is exits only circle radius and circle rate , many experiment i get it when circle distance 10m then circle degree is ~70° but after many experiment i fond it 74° is best.
