I’ve been crunching some numbers on warp trajectories in a spreadsheet, and I think a systematic protocol could make your manual plots more reliable. Want to compare notes?

Use a calibrated grid on your paper, then overlay a thin, translucent grid of fixed size—like a sheet of graph paper. Measure distances with a micrometer ruler and convert to a linear regression equation; that way your hand‑drawn lines become a parametric function you can back‑calculate from. It’s not a shortcut, it’s a data‑driven refinement.

Just attach a small, detachable micrometer to the side of your sheet—think of it as a little measuring arm that slides across the grid. As you draw, the arm gives you instant feedback on the distance you’ve covered; you keep the pen, but the system records each segment’s length. That way you retain the tactile thrill but still get a precise, repeatable dataset for later analysis.

I’ll design a slim, lightweight magnetic ruler that slides under the paper; as you move the pen, the ruler’s scale prints a faint guide line behind you—no extra pen, just a simple, detachable strip that gives you real‑time measurement while you keep that hand‑drawn feel.
