Problem with Jobo ATL 1000 programs

Hi everybody! I'm new here.

I just bought a Jobo ATL 1000 and I've some questions.

The times of the ATL1000 programs can't be changed, you can only modify the first step of the developer.

I'm using Fuji X-Press C41 kit right now, and the times they say me are:

-Developer: 3.15 minutes.

-Bleach: 6:30 minutes.

-Rinse: 2:30 minutes.

-Fixer: 6:30 minutes.

-Final rinse: 2:30 minutes.

In the manual of the ATL 1000 they use these times for my process:

-Developer: 3.15 minutes.

-Bleach: 6:00 minutes.

-Fixer: 6:00 minutes.

-Final rinse: 2:30 minutes.

My question is: 1) Is there any way to change times without reprogramming the chip (I saw the post but I don't know how it is done)?; 2) Will something happen to the bleach and the fixer if they are 6 minutes instead of 6.30 minutes?; 3) And what would it happen if I reuse C41 chemicals using the Jobo ATL 1000 program? I mean, Fuji says Bleach and Fix need a rinse, but what would it happen if I don't made the rinse?

Sorry for my English! I hope you can help me because I'm starting to think that I made a bad bought
