For any limited-time championship, you pretty need to decide to go-all-in-or-bust almost immediately once the completion PR requirement is released.

If you do want to go all in, you have to start upgrading immediately and keep upgrading till you meet the championship's PR. Always look at the upgrades strategy to know which upgrades to go for.
