Another quick and dirty solution being a week with no cards, might work pretty good as a first week for Dom if the season is ending in 3 weeks since in the first week the brackets will be so mixed and potentially one sided anyways if there is only one serious player in any of them and any medal gain could be countered in a few weeks. Another option to prevent this is to have everyone put into 2 Dom brackets, one that they have no access to and awards no medals just for number tracking, though that brings up the same issue of calling up the table all the time.
