Since data at the current point in time is still being processed and takes about a minute and a half to complete its way around the system a way to add a data point from a few minutes ago for example would be very advantageous.

As a work around currently the metrics all do a
where utc_date between
dateadd(minute,-3,convert(smalldatetime,getutcdate()))
and dateadd(minute,-2,convert(smalldatetime,getutcdate()))
but this means that the data is always two minutes out when compared to the actual raw data
