A bit late replying to this lol.

However. One key point is that the vote level for a witness getting to the top 20 should not have any bearing on the voice of the platform, That is were everything falls down.

While the top witness will gain a higher reward. This should not also increase the value of the voice spoken. A higher SP vote to a witness can get them to a top position, But like in all elections after that vote is cast, All witness should have an equal vote on changes. Without this Slavery ensues or a class tier system were only the wealth is listened to.
