How Much Backlog To Drop At Once?

I'm releasing a series I've been writing for mostly just me and a friend since 2019 and finally starting to try it out on RR, released the prologue and first 8 chapters at once and have it on just daily releases now.

I've heard about swaps but I have no audience (except my friend who gave me my 1 review), would just dropping more of my backlog each day help with building a little traction?
