Use the data from http://www.clarkvision.com/articles/digital.sensor.performance.summary/ as it appears more accurate. Ignoring H1 and H2 ISOs.

Using a raw data viewer, you can see that the white point is lower for ISO 100. It is actually 1/3rd stop lower then ISO 200. Since the true sensitivity of ISO 200 is 160, this puts the true sensitivity of ISO 100 @ 125. There is clearly some digital manipulation occurring which shouldn't be the case for a true analog ISO.

Using the data from clarkvision reflects the DR lost with this digital wizardry.
