I think its important to put things in perspective. Look at the largest/most popular accounts on NOSTR (Odell, Hodl etc) and look at their average engagements on a post.
Often its dozens of comments, handful of zaps and reshares - that's a more realistic judge of their followers vs a follower account.
This post of yours is doing comparable numbers to some of the largest accounts on here.
