David Beckham to miss a penalty in his first season - 10/1 - 2pts

LA Galaxy have 20 of 32 matches left this season. Give his pivotal role at the club, I think it is likely that Beckham will take the penalties at LA Galaxy (he has been a penalty taker for some of his previous clubs/country). If this is the case, then the 10/1 at Stan James that he misses a penalty at some point during the season is great value.

(See analsysis below)

The conversion rate for penatlties is approx 80% (0.8)
The % of matches with a penalty = 25% (0.25). No. of penalties that LA Galaxy expect to receive in remainder of season = 0.25 x 0.5 (they receive half penalties in matches) x 20 (no. of matches) = 2.5
Probablity that a penalty is missed (2 penalties, conservative) = 1-0.64 = 0.36 i.e. approx 2-1 chance.)

Chris,

This may sound naive, but can you explain the points thing? Is that the percentage of your stake that you bet on any given punt?

Took your advice on Murray for Sports Personality of the year and got it at the price you mentioned.

Regards and thanks,

Michael

1 point for me = £25 - I bet in points as it it it the % profit that is the challenge.
