In the future, here are some criteria for taking or tying for the lead:
1. Abundy takes lead from JK with 1,537,501 or more cases.
2. jb777 takes lead from Abundy with more than 2,525,000 cases if there are more than 120,000 deaths.
3. Valuist shares lead from Abundy with less than 2,900,001 cases. Leads over jb777 if greater than 2,900,000 cases, but both need less than 105,000 deaths.
4. Valuist can't win if more than 105,000 deaths.
Other situations will depend on actual cases and deaths.
