If anyone wants a guide to how to discern the numbers of the Straw Hat Crew, here is one. Note this is my interpretation and is not official. It should line up with chapters. Note that chapter names do not line up 1:1 with crew members. An example is Chapters 648 and 967, neither are called "ninth person". If there are inconsistencies please clarify.
0th: Luffy (he started it, refer to end of Ch 1 for the "10 mates" thing)
1st: Zoro, right-hand
2nd: Nami, navigator
3rd: Usopp, vice-captain, Sogeking, Marksman, Lookout, God
4th: Sanji, cook, perv
5th: Chopper, kawaii, boku wa doctor
6th: Robin, best girl, Poneglyph reader
7th: Franky, chad, shipwright
8th: Brook, perv 2, musician, skeleton
9th: Jinbe, chad 2, Helmsman, fish
10th: Yamato, quartermaster, apprentice, trespasser, Momo's envoy (im sorry I dont think their potential role matters all that much, it might just have something to do with the Journal)
unlisted: Vivi (best Strawhat), had to stay behind in Arabasta, if Yams doesnt join she's already coming on board.
Tried to line it up with the chapter titles.

If you go by the SBS numbers, then Jimbei's number 10

Guy's a pseud
SBS would not line up 1:1 with canon. Ie it would just keep adding up numbers. I still think the reference point is Chapter 1
