The problem with doing that isn't just artificially inflating the rating, but it also ignores the fact that the first few chapters are
supposed to be attention grabbing in order to draw in readers.
And honestly, this first chapter is pretty generic. Good to kill a few minutes, but nothing that hasn't been done 6 times before with minor changes.

Most audience rating systems are pretty broken. People don't usually bother voting unless they absolutely hate it (1-2*) or love everything about it (9-10*). In theory they'd somewhat balance each other out and leave the other reviews to swing the rating to its "real" score, but there's always much more of one which heavily skews the rating.
That's not even taking into account how subjective any rating system is to begin with. A 10 for me is "practically perfect in every way" (I've only considered 3 anime to be a 10), but for someone else it could just be "I liked it".
Or how I've supposedly been rating things wrong my whole life. I think a 5/10 is in the middle and therefore average, but my friend sees that as 50% which is an "F" making it garbage. I think that's dumb, but that seems to be what a lot of others go by as well. That's when most of these ratings started to make sense to me.
