The bet in play odds for the top drivers during the Spanish Grand Prix.
Usually when I have a bet on formula 1, I generally prefer to wait until after qualifying as by this stage of the weekend the form of the various teams is starting to emerge and it's therefore possible to make a more educated guess as to how things will turn out. It's quite rare therefore that I'll have a bet before qualifying and even rarer again that I'll ever bother with 'bet in play'.
However, just for a change, during the Spanish Grand Prix I monitored the 'bet in play' odds every few laps to see how the bookies resasessed their opinion of the potential winner as the Grand Prix progressed. This is a graph of the odds:
