One downside of AVW which stands out is that lower POS difficulty lowers the AVW which could encourage whales to not stake or for parties to dos staking nodes to lower AVW. During hardfork/mandatory upgrades this AVW might be an unstable value.

Perhaps instead of 'TotalMoneySupply' in TVW, a more appropriate value could be the the sum of coins on addresses with coin-age less than a year? That would take destroyed coins and deep-cold-storage coins out of the equation.

Project Work Availability Score is green

A public attempt at contact with a project admin is made

I'm not 100% on board with this, with the team-req still in place it's very easy to trigger flamewars/drama if you're making a public plea to 'do/change x or lose whitelist status' people can get rightfully defensive at an outsider making ultimatums. I got banned from bitcoin utopia for asking them to implement SSL for example.

Perhaps the onus to reach out to projects for whitelist retention is on those interested in keeping the project on the whitelist? Rather than the person proposing the poll, who'd be probably biased towards whitelist removal.

IMO you aught to have the right to throw any project to whitelist poll for any reason, if it fails to meet the min reqs then would go nowhere as per the poll definitions, right? It shouldn't be solely reserved for when there is some major incompatibility (like mandatory new features).
