It scares one sometimes that live feeds of quantitative data via online summarized metrics dashboards are: a) reliant
on alogrithms / formulae constructed by humans b) may only reflect a point in time that is transient and needs to be somehow replicated
accurately later in the future if needed for evidence c) may
draw upon real time data from multiple sources for different parts of the
screen (via widgets) d) data source quality needs to be interpreted against the data owner's original meaning of that measurement and criteria.
