ADE7816 Overvoltage Detection.

I'm wondering does the VGAIN register impact on the Overvoltage Detection threshold calculation, or does that run before the VGAIN runs?  If it does impact it, what's the formula for calculating the revised threshold setting?

 

And ditto for the Peak Detection stuff?

 

If I've calibrated a bunch of 7816s using VGAIN so that they all give exactly the same Vrms reading when monitoring the same signal, will they all reveal the same PEAK DETECTION value (subject to them monitoring the same cycles), and will they all fire their OVERVOLTAGE interrupt at the same time as well (given identical threshold settings)?
