BIG BROTHER 11 BETTING UPDATE: RACHEL A LOCK FOR 7TH EVICTION

We're seeing plenty of movement in the Betfair markets for Big Brother 11 and it is becoming more and more apparent that Rachel is definitely set to be the next housemate out the door. 
In regards to the betting market for the 7th Eviction on Big Brother 11, we've got Rachel's price now plummeting down to 1.27 from around 1.5 yesterday. John James' odds to be evicted have risen to 4.0 while Dave is completely safe at a 16.5 price. He's the only contender not listed at 100.0 or 150.0 to be the 7th eviction. 
It doesn't look like Rachel has any hope of staving off eviction and somehow finishing in the top 4 as her price is trading at around 11.0 to finish amongst the top housemates. 
The contenders listed at odds-on prices are Corin at 1.16, John James at 1.23 and Josie at a 1.44 price. Steve is the closest other contender at 2.2 while Andrew is just behind at a 2.66 price. Dave can be backed at 3.4 and Mario is trading at a 3.8 price. JJ sits at 3.65. 
The position of top female looks like a two-way duel between Corin and Josie with Corin priced at a solid 1.59- I actually think that's a pretty generous price as she's not listed at much more than that to win the show outright. Josie is behind at 2.62 but I can see that price moving higher in the coming days. 
The race for top male is skewed heavily towards John James and he's just above even money with a 2.02 listing. Dave looks like the big spoiler at 5.0 with Sam just behind at 5.4. JJ is trading at 5.6 with Steve at 6.6. 
A female winner is favoured to win with a 1.59 price ahead of a male winner at 2.14.
