Our procedure is as follows:
We stick to the original numbers until January at which point the winner are declared on the original numbers. This is more fun than having weekly adjustments throwing everything off.
Also in January we can start looking at the final numbers and a final winner is declared after all adjusments, this will probably be done in October of next year before the new Countdown.
My Excel sheet allows me to easily switch between Original and Final numbers. Looking at the adjusted numbers now yo_john117 won both weeks.
