Custom field calculation for bracketing std with overlap

I want to calculate %variation between 2 bracketing std's. I've made one for %var between 2 sample injections in another project but the labeling for samples is unique because it is used only for that injection. the bracketing std 2 is used for the calibration curve of the first (std 1 & std 2) and second (std 2 & std 3) sample group

Setup:
std 1
smpl 1
smpl 2
smpl 3
std 2
smpl 4
smpl 5
smpl 6
std 3

    When you say % Variation, do you mean %RSD of area between the 2 bracket standard groups?

    %variation is calculated with area --> (std1 - avg std1&2) / avg std 1&2.
    If it was %RSD I would use the report

    Hey dhes,

    Is it not the %deviation from your calibration curve what you are looking for?
    That is your response (probably area) and calculates the deviation from your average point of the curve.

    So it basically does what you want..
