That's using these settings:
Phase1: 30, 20, 18, 16, 15.
Phase2: 750, 450, 400, 250.
Phase3: 450. (450,450,450,450).
It could be possible to do better by tweaking Phase3 further, something like:
Phase3: 550, 350, 350, 450.
Phase1:
Get counter.
Get as many people as possible on zero, by creating other members with counts.
Phase 2:
Group the tokens together in powers of 2. Starting at 2 and ending at 16.
Phase 3:
Count all remaining tokens.
For Phase 3 to work you need to allocate time to count all the 16 grouped tokens to the counter, then all the (remaining) 8 ones, 4 ones, 2 ones and then all the single tokens (there shouldn't be any, but it can happen that there is).
