@Icarus:
When he beats Doffy it will be enough, it will show his increased threat to the WG and that he has grown beyond what he was when jimbei saw him last, that will be enough evidence to show that at the very least Jimbei is no longer stronger and that is what is required before he can join. Power levels are meaningless in this manga but Doffy's scalp will show that Luffy is strong enough to have someone like Jimbei in his crew, if you ask me I suspect that both Zolo and Luffy are stronger than Jimbei now on land (remember he fought Ace to a standstill on land pre timeskip), but they will never be as strong as he is in water which is why he is so valuable as a new nakama.
Jinbe was never at a Handicap fighting Jinbe and as mentioned by Katztarr, it is getting in to, TOO techincal.
You can find our discussion a bit earlier in thread

Find out where it starts, me discussing this with Katztarr, so we ended up with a conclusion.

@huron:
so when can we get the chapter 732 spoilers?
What you quoted there is the PUBLISHING SCHEDULE, this is a day before the scanlations come out, you should look at the other section, the spoilers should come out. So the spoiler will come out in about 50-55 hours from now. The translated chapter will come out in about 75 hours from now.
