I do not agree.
If 10 people joined up together on the main pool you still wouldn't get such a large share of the prize. as the rest of the pool takes a slice too.

Here if we team up some hashrate the payout would be much much better.

If that were not the case why would 10 people throw 0.125 btc at a "shot"  at the block.
Why not just point hashrate at it?
