This is something we experiment with for visualization of concurrent-reliance-temporal data. A very brief explanation:
Sheet for Positor: 1 and attribute: InflationPositing Changing timetime 2012 2013 2014 2015 2016 2017 201820150101 1.0 1.2 1.5 1.2 1.420160202 1.1 1.7 1.4 1.5 1.620170303 1.3 1.5 1.8 2.0 2.0The above would be a sheet, showing both with version is in effect at different times (changing time) and what corrections have been made (positing time). There is one sheet per attribute and positor, since a different positor may have a different opinion about the values.
