A workflow pattern for systematically testing a numeric ComfyUI parameter (e.g. Max Shift) across a range and getting a self-labeled comparison grid, rather than eyeballing one-off changes. Converts the target parameter into a node input, drives it with a float-range node stepping across a sequence (e.g. 0.75 to 1.75 in 0.1 increments), converts the resulting floats to strings, and overlays that text onto each output image (extending the canvas ~50px to fit the label).
Originated as a workflow for sweeping Model Sampling Flux's Max Shift/Base Shift values, but the pattern (float range → string conversion → text overlay) generalizes to any numeric ComfyUI parameter sweep.
To batch-test a numeric node parameter: expose it as a node input, feed it from a float-range node stepping through the desired values, convert each float to a string, and overlay that string as text on the corresponding output image so a full batch can be visually compared without manual bookkeeping.
