Sport mode radar display question

[GRUAVP4Pro]

I flew in Sport mode for the first time yesterday. The radar display had a dashed green arc around the lower right corner and was displaying a percentage in the circle. The percentage varied from about 20% to 27%. I didn't know what those meant. The percentages don't correspond to the aircraft or controller battery. The green arc didn't seem to correspond to the aircraft's position. Could someone help me understand this information?

If you have a big enough tablet, under the percentage it shows the word power.
It's how hard your motors are running.
