One dive, drawn against its limits

The same pressure space as the gradient-factor chart — ambient pressure across, tissue tension up — now with a dive traced through it. Press play and follow the leading compartment: loading at depth, crossing above the ambient line on ascent, held at a stop when it meets the GF 30/85 line, surfacing beneath the GF High ceiling.

A schematic, not a computed profile: axes are unscaled and the dive path is drawn for the leading compartment only. The vertical marks give tissue tension as a percentage of the surfacing M-value gradient — the quantity GF High limits. With reduced motion set, play shows the completed dive at once.
