The problem is not with the way the SP is calculated, it is a very big problem with giving punters the option to specifiy odds limits or specify no limit.
This is really what causes the large majority of distorted SP's.

Imagine this scenario, I've seen it happen in smaller markets....

Horse is trading @ $2.00 on Betfair.
Punter wants to lay it at SP for $5,000 with no price limit.

Backer wants to back it for $1,000 with a limit of $10.00 (greedy sod).

There isn't enough liquidity in the SP so $1,000 of the $5,000 gets matched at $10.00.

Backer is doing cartwheels, layer is totally ************ed and SP returned is around $4.00.
