How much is too much?! (Patreon)

So I've been thinking about the structures and lengths of the current stories for a while now. While some of them are pretty packed with content and others still in the early stages, I don't think it would be good if they dragged on and on. So I've thought about an approximate number of parts for each of them. I'll leave them down below. Tell me what you guys think!! 

1. When muscles rise - 15 or 16 parts

2. Debra's progress - 10 or 12 parts

3. The biggest stud in town - 8 or 10 parts

4. Rune of muscle - 2 parts
