I've seen some indie authors splitting their novels into three works, naming them "Title - Part I", "Title - Part II" and "Title - Part III".
It seemed like it's a good idea since you're giving more material to your readers much more frequently, which doesn't allow them to forget your name. But I've no idea if those shorter works sell well. As long as it didn't sell less than 3 times than the entire novel at once format, it would be a good idea.
Wether I choose to split it into parts or put the entire novel at once, I intend to charge only $0.99 for each work.
Shortly put, I was wondering if this a good idea to put into practice, in terms of royalities gained.
