in-running bets matched at worse odds than my offer price

Thanks again to everyone for your input

Looking again at the graph the lowest prices matched were quite early in the odds history. If that graph history is taking in the whole day and not just the in-running market then perhaps that explains things.

Have a look at the BSP prices file dwbfpricesukwin01022020.csv for the day obtainable here (note the date in the file title is the day the file was prepared, the next day, and not that day's racing … don't ask!). For By Rail in the 16:20 at Lingfield on 31/01 it gives the lowest In-Play odds as 48 and the lowest Pre-Play odds as 27. So it didn't quite reach the highest of your range for Dobbing.
