MC - Publications Concern

Hello,

I am ready to apply for stage 1. I am just stuck with 1 of my document which is publications under Mandatory criteria.

I have published a book on amazon kindle but I am not sure how assessors analyze its impact. I have included the number of downloads but they also consider the ratings of the book and I dont know around which number is good enough for ratings 20,50,100.

Looking forward to feedback from you all

Thanks in advance
