Starting Price of Grand National Fav. to be 5-1 or less.

In the past 20 years there have been one void National and 4 National favourites 5-1 or less. It is therefore suprising to see William Hill offering 12-1 on a 5-1 fav (or shorter price). With the recent policy from the handicapper of 'compressed' wieights, you could argue that a short priced favourite is less likely. However, jt. favs 5-1 favs last year of Hegehunter/ClanRoyal shows that this may not make a signficant difference.

For this reason, I hoping for a big plunge on any horse... I'm having 4pts at 12-1 on a 5-1 or shorter price Grand National fav.
