Thanks for that link, it was usefull. Our last tourney meets the recquirements for a K-24. Who can change the results ? (tourney has already been processed).
Just because it meets the requirements for a 24k tournament, it doesn't mean it must be 24k.
If the TO chose 16k, that's what the tournament will be.
If the tournament has been processed already, there isn't much you can do.
You could e-mail
dci@wizards.com to ask them for any possible action, but I believe you are stuck with what you have.
