Almost certainly not. It's just a reflection of the bets the bookies are receiving in order to balance the books on their end. Which is why a small market like BB fluctuates so much so quickly - it doesn't take much money to shift the odds significantly.

I suppose that means Tim isn't exactly set in stone, still his odds are pretty safe.
Hopefully Tahan or Jade can upset him.
