but if they’ve been here since 2018 and only have 300 hive power
I think this is solid. There's no excuse to be in the network for 6 years with a good rep and have only 300 HP I think no excuse can actually justify it. I do look at metrics like this and it actually makes me to increase or decrease my Curation activities for some certain account.
I don't think my VP has hit 100% in a very long time, perhaps in over 12 months I don't think it has, I believe. I do this by having auto votes.
I like your criteria too, and it's fair enough as well.
