BSP a lot lower on r1 and r3 at Musselburgh on the winner, are people getting an in-play advantage at the start?
Yesterday Betfair's feed was about 6 seconds slower than the RTV feed and they were turning inplay off their own feed , probably the same today

If the winner got a decent start I'm not surprised their BSP is lower than ISP. Getting as bad as the Aus racing where they're going inplay later and later, about 3 races at each meeting will return a BSP lower than the industry ISP. Some as high as 40% lower than best tote prices, all well and good saying 99.9% of the time BSP returns better than ISP but not much use if that's on the losers.
