Not sure if the previous versions did this but in V7.3.1, if you have an alternate calibration file open for comparison and you view the VE data from the alternate calibration file, the cylinder volume of the "calibration file" is used to calculate the VE table of the alternate calibration file when veiwed as a %. I guess this is only apparent if you are looking at calibrations with different cylinder volumes.

I thought I was loosing it for a minute there.
