Question about team rules

By Fatespinner, in Grimm RPG

Hi,

I have a question about the team rules, I am not sure if I understood them correctly. Does every 6 count as a raise or just one?

Example:

Tommy want to climb. He has a rang of 4 to do this and his four friends help him. Now they all roll the dice: 3,6,1,2,6.

What interpretation is now correct?

a) Tommy gets a +2 and may roll the two 6's again. Basically everybody rolls alone for a bonus using the normal rules

or

b) Tommy gets a +1 and may roll the two 6's again.

tommy gets +1 and also gets to roll two dice again (assuming the boost range is 6).

A spin on this, by the way, is that you get a +1 or -1 for every 6 or 1, and only rerolling if every die gets a 1 (but still rerolling every 6).
