Eslyna Not to sure what vpc is, sorry.
I guess for me, this collection to views is about audience reach.
Webnovel has a very specific reading market. If your story fits to their market majority and popular format, it's likely to gain reads and a solid ratio.
I guess I'm not inclined to say that this ratio defines a quality story (grammar, design etc). How many complaints has been made on this forum about some promoted and popular works being poor or so so quality? Then again, most readers here are forgiving in that sense.
I do agree on the need for reflection and continous improvements, but there's also the risk of doing too much to suit the masses that you'd loose yourself to the audience rather than the other way around.
You noted some interesting perspectives. Thanks for sharing them. Good job on the stories.
