I don’t think those 80% are going to be accurate. So far, I’ve been getting about 1vet/day for eu1 and us1 (a little less for us1) and it doesn’t seem strongly correlated to traffic or storage from these nodes. There were recently a few days with higher vetting (3rd of March to 7th of March) but it has slowed down again.
I have a discussion with @BrightSilence about that here and they are looking for other people to post their weekly vetting progress to allow for more precise estimations. Feel free to participate
