One of the tabs is marked SPADs - clicking on this brings up "category
A1 SPADs and MAT" What is MAT in this context? (SPAD = Signal(s)
Passed at Danger)

Not too sure. The monitoring of anything is done in periods which are four
weeks long - the start of period one normally corresponding to the start
of the tax year. This gives 13 periods per year. They've displayed the
totals per calendar month, so the M probably means Month and the T Total
(Monthly Actual Total?).

I see they don't exactly give the latest figures, the chart ending in 2002
compared with their other information which is (still rather behind) shown
for August/September 2003. Mind you, they stopped updating the SPADs
details on the SPADs noticeboards at work after last April's figures so
perhaps they don't want people to have the latest information.

MAT stands for Moving Annual Trend.
