2-Bar Scaling - Questioning the validity of 2x

I have also added this data to the 2Bar SD 'sticky' above. As you can see:

Click

The 2Bar Map sensor does not scale at 2x across the range of measurements taken by a 1Bar sensor. In fact, the 2Bar sensor delivers its 30-100kpa voltage across the 30-65kpa range in the 1Bar sensor, which would significantly affect the initial tuning attempts when switching to a 2-Bar tune on a 1-Bar car.

I think this information is important enough to justify it's own thread, although I will admit I may be interpreting the data wrong. Any comments?

Cheers!
