skill cooperation and # of allies that can help

[Particle_Man]

It says "up to 4 allies can help you, for a maximum bonus of +8" under cooperation in the skill section on p. 179.

Does that mean that only 4 allies maximum can even try to help you (so a fifth ally would not even get to roll the d20), or does it mean that more than 4 allies can try to help you, but no more than 4 allies' successes will be counted (so all 5 allies roll a d20, but you only count 4 successes even if all 5 allies make the DC 10)?

 

[Simon Marks]

It says "4 people can help", but nothing about how many people can try.

Look at the situation, see how many people can actually try to help. Adjudicate.
