   I haven't read the code yet, just reading comments and responding to my tag from @a2l007
... I do think it is very helpful to keep the `percentOfSegmentsToConsider` value. Our largest
cluster has over 2MM segments with replication and slashing that value down has allowed us
to cut a large chunk out of coordination time in this phase by short circuiting at what we
have deemed to be an acceptable point in the iteration. I'll try to read through full PR today
and update my comment
