Percentages on CALENDER?

Ok, so I'm looking at the forecast/actual/previous percentages on the calender charts.

Since Forex doesn't ever "close" what are the percentages based on?

The previous days price at the same time of the report? Or the time that particular country closed?

Example of what I'm talking about:

4:30am GBP GDP q/q (r) http://www.forexfactory.com/images/m...mpact_high.gif
0.8% 0.8%

so, the expected and previous change was/is 0.8%

0.8% of what? LOL

The GBP is the currency of the country the news item relates to ie UK
The GDP is the news item
the % is the previous and the expected increase/decrease in the news item.It doesn't mean the GBP is expected to increase by 0.8%
