Personally, I don't entirely agree with rewarding magnitude decay for a removed project. The goal is to work toward rewarding actual work done. Rewarding decay is not this.
One could argue that the rewards from decaying mag are exactly equal to the rewards "lost" during the initial buildup of mag, see the plot in @parejan 's comment on this post. In that sense it would be natural to continue rewarding decaying mag. This is an ugly solution though. I hope many of these problems will be swept away by a successful implementation of the roadmap proposals.
I was waiting for this response! = )
In my opinion, the possibility to exploit payout for power-down (due to the likelihood of a lower pool of users working on the project) outweighs the benefit to paying mag lost during charging.
In general, I agree and also hope the proposed roadmap developments will look to solve these issues.
I think there would be some ways to further develop this but as we only have limited resources available, it would be more beneficial to use them for new developments in the proposed roadmap instead of using these resources for temporary fix. I think we have the same position here...
yup, seems like we're one big happy echo chamber = )
