Thank you for looking into it.

1- If the pool is labeled as 5n then the block needs to be paid 5n.  It is a simple calculation that can be done by hand since the number of miners is small and all of the blocks shares are counted.

2- If it is left the way it is then many people will not get paid as described in the OP.  Sure I would like to get the 1/3 of a Bitcoin but I certainly do not want it to be paid from your pocket.

3- Voting on it is a great option but a predictable one.  Those that are negatively affected will vote one way while those positively affected will vote the opposite. I suggest you look at the info and make a decision, people are going to be unhappy either way.
