I can understand why you need to do this, to keep the people at the top happy, but also their sponsors happy too. Without that then hwbot wouldn't work at all.
I agree that some sort of additional reward for users who get the highest scores is good, but the initial suggested figures are a bit high. I suppose like everything with rev3, it just needs a little bit of tweaking to get it right. Most importantly though, people need to stop moaning and get on with it. This is only going to affect the top people, not me, so I'm not bothered at the end of the day.
