In the Run Menu, if an event selected is a qualifying round for an in-lanes race where it has been set-up to advance runners by Place and Time, the Advance Formula button will be active. You can then alter the advancement formula in case the wrong one has been selected or the number of heats has changed and a new formula is required. Click the Advance Formula button or press F9, and you will be able to change three items:
The number of heats to be advanced to the next round
The number from each heat that advance by place
The remaining number that advance by time to fill the advancing heat
Advancement formulas appear on Draft Heat Sheets created from the Seeding Preview.
