Can groups train for Spiritken?

I'm just elaborating on what Trunks already said.

We look at the individual efforts of the members of a group. It doesn't matter how many people there are in a group, it matters how the specific people do, since specific people earn the technique. The more people you have, the more the roleplaying is spread out. The more the roleplaying is spread out, the harder it is for you to really show you deserve the technique.
