Ok here are a couple of unscientific, but reasonable (atleast to me) ways
to do set the initial "weighted average" rate for current participants
with my vote being for option (1).
Just use the participants current, unweighted, overall average.
Drawbacks: It will take time for someone with a large difference between
their current rate and their overall rate to reach the "correct" value.
Just use the participants current day's rate.
This is like saying everyone started the same day and doesn't take into
Drawbacks: Sneakernetters who didn't submit blocks the day this starts
will start with a value of zero. People hoarding blocks will start out
with a large number if they happen to submit their blocks on the right
(3) Not quite as simple:
Arithmatic average the participants current rate and overall rate.
This helps the people with higher current rates than their overall,
unweighted average reach the "correct" rate sooner.
Drawbacks: People with larger overall rates will have a higher rate than
is "correct". (Is this really a bad thing? Everyone likes to feel good
Just my thoughts on the subject.
