Amounts matched dont tally with pop up market info

[OliasOfSunhillow]

Why is it that the amounts matched at avrious prices as returned in the 'size' field when interrogating via listMarketBoo, do not tally with the pop up you get when checking manually on the site. They look totally out of kilter. Today at 1pm Peace and co was trading at 3.7 and then plunged to 3.15 over fifteen minutes. The pop up box confirms that it never was laid above the 3.7 and yet the data coming back from the api says it was laid up to 4.1 before dropping. I am pretty sure nothing was laid at 4.1.
Anyone any ideas

Have you noticed this before?

I know there were some issues with betfair today. These may explain what you saw. In this case the website might have been showing old data.

I will carry out some further tests and get back. This is the first time I have actually looked at this data
