When asked on Juicestorm he said he hadn't paid any yet. Also he runs a mile if you ask him.

Read a post recently that he only made 28k in the last 12 months?
While I guess that is respectable, it certainly doesn't fulfill his "status" of how he is received over there.

And I do apologise for posting that link. I just felt it had to be done considering it perfectly showed exactly what I was trying to describe. Didn't want to be seen as infringing any "copyright" (plaguerism?) issues.
Not trying to cause any trouble, and respect your decision to delete the link. I am, afterall, a long term BetAngel devotee, and likely to be in it for life. Or at least as long as you will have me. :)

No offence taken, it's important to discuss these things. Betfair indicated to us that they will introduce a feature where you can choose to display the true odds or just the unmatched ones. We are just sat here waiting to hear from them.

FYI, There is a section on Betfair now that describes how this works and with full calculations: -

http://bdp.betfair.com/index.php?option ... &Itemid=62

We are told they have no plans to put this data through the API "for months". So even if we implemented a version that displayed this information you would still be unable to act on it. It doesn't seem to be a very high priority for Betfair.

A re-worded statement from Betfair regarding this:

http://bdp.betfair.com/index.php?option ... Itemid=108

Why are the prices displayed on the website different from what I see in my API application?

The Betfair Sports Exchange tries to match bets against the bets placed by other users as well as equivalent bets where possible. These "virtual" bets follow the rules for cross-matching posted in the Betfair.com Forum. For example, if a customer backs Player A in a tennis match at odds of 2.0, the exchange matches any lay bet at odds of 2.0 or better on Player A. In addition, the exchange also calculates all possible matches that are equivalent to a lay bet on Player A. So, if a customer backs Player B at odds of 2.0 or better, the exchange matches it with the back bet on Player A.

The Betfair website calculates the possible virtual bets that the Betfair Sports Exchange creates and displays those bets as if they were placed by other customers normally. In other words, bets displayed on the Betfair website may be actual bets placed by customers, or virtual bets that the website knows the Betfair Sports Exchange will match due to the cross-matching rules.

At the present time, the API returns only actual bets in the getMarketPrices, getMarketPricesCompressed and getCompleteMarketPricesCompressed services. The API does not include the virtual bets that the Betfair Sports Exchange creates for cross-matching.

NOTE: It is important to understand that bets placed through the API are matched in the exact same way as bets placed on the website. In other words, a bet placed through the API is matched with either direct opposite bets or with the virtual bet, if available.

Therefore, you may see prices displayed on the Betfair website that are not returned by the API, however the Betfair Sports Exchange still matches any bets placed against all bets and the equivalent cross-matched bets.

You may see this on all odds markets on Betfair, except those markets which may have non-runners (for example horse racing win and place markets), as well as markets which may have runners added (for example golf tournament winner markets, next manager markets etc.) Bet matching does not apply to markets run under our Tasmanian licence.
