Well spotted, indeed he is. (@Scylla: maybe you can prove otherwise, but I've just done the math and it's pretty obvious.)
For now I will not retract any bids. Scylla is hereby forbidden from bidding until he is back within his budget. If nobody overbids and he signs them all, only then the Cancellara bid will be retracted and the clock reset.
Also, a warning to Scylla for this unfair move. First warning has no consequences, it can happen to anybody. Second warning equals a penalty.
