Tom and others are more qualified to answer this but I think generally one uses the same gamma targets for all stimulus levels except when calibrating to BT1886. That said, at times I've calibrated...

I'll let others answer questions 1 & 3 but as for question 2.....Gamma is calculated from the 100% reading. So yes, gamma readings are sensitive (dependent upon) the 100% reading.

Tom,

What is the build number of this latest build? I removed 2.5.5.38xxx and downloaded 2.5.5.190. It seems like this should be an earlier build but that makes no sense???

Did something in the HDMI chain change since you last used the '57 (or was this the first time you fired it up)?
