There is one thing you are leaving out -- the underlying reason why someone has this power is that many people have included the person in their trust list. Those who are on DT1 is (somewhat) random, and does rotate, however the people who are on DT1 are not arbitrary, they have effectively been chosen by the community to have this power.
Indeed, they have been chosen by
a very small minority of the community
Just 10 people (with some earned Merit) is enough to put someone on DT1, after which they can create as many DT2-members as they want, or downvote all other DT1-members.
Of the 133 people who are eligible to be on DT1, how many people included them on their trust lists that have 10/100 merit (how many people actually played a role in selecting those eligible to be on DT1)?
The requirements are 250 Merit for a "supervote", 100 isn't enough.
Of those who potentially can play a role in selecting who is on DT1, how many people have no one on their trust list who is eligible for DT1?
I never checked, but (using
data from a week ago), there are 811 users who've earned at least 250 Merit, and 11,650 users who've earned 10 or more.
How many people who are potentially able to play a role in selecting DT1 have a trust list, but no one on their trust list is eligible for DT1? How many accounts are actually active by various metrics (such as making a post in the last 60 days, logging in during the last 60 days, etc).
I can't answer all your questions, but 3 years ago I made my
DT1-election: Rank up pipeline:
loyce.club/trust/ranking/ shows that 477 users are included by at least one user with 10 or more earned Merit. Those at the bottom of that list are very far from reaching DT1, but 219 users have enough inclusions from users with enough Merit to qualify for DT1.
