No, that small number surrounded by a grey circle is just how many people have clicked on that link. For some audios I put suggestions for how many times to listen to it as x1,x2,x3 etc.
For example in this stack the audios have x1,x2 or x3 next to them.
If I didn’t put any number next to an audio, usually it means there is no suggested number of times to listen to it by Sapien Medicine.
Usually the suggested number I put is what Sapien Medicine suggested for an audio. Rarely I might put my own suggested number.
