TOC rest, from the FAQ:
#701 Tournament of Champions
Q. How is rest issued in between rounds of the TOC?
A. The only rest provided in between rounds of the TOC is if you knock off your competition in fewer games than your next round opponent. For example, if you sweep your first round opponent in 3 games but it takes your 2nd round opponent all five games to advance to the second round, your team will receive 2 games of rest. Rest is provided when the next round of the tournament is scheduled.
