SCCA rescales the aim against this job's own paper white (measured Lab untouched); ◀ marks the total counting toward the score, currently uncorrected. Beer's Law columns are the best density found in a 30-step sweep, ki 0.820→1.255.
Net ink optical density scaled by ki in 30 steps of 0.015. Each circle is one simulated density. ● Beer's Law optimum (lowest ΔE00); ◆ the actual measurement. Dashed lines mark ΔE 1.5 and 3.5.

Murray-Davies tone value from Status-T density. Score per cell: 2 if |ΔTVI| < 2, 1 if < 4, else 0. Total 6/8.
Murray-Davies tone value from Status-T density, plotted as gain over nominal. Green is the aim standard's own curve; the coloured line is this job. Both are pinned to zero at 0% and 100%.

Gray total 11/11. K50's tone value here is the tristimulus Y ratio used by the gray-balance side; the TVI table above uses Status-T density instead, so the two K50 numbers differ by design.
Not available for this chart: its gray tones are single patches, with no C+/M+/Y+ probes around them to regress a Lab→CMY correction from. The ICC route was not available either: need three gray tones, have 1 Measure a CT36 chart for the measured-gradient correction and its .acv curve.
