Top-down view centered on the Incense Altar. Click or drag to place the selected block on the chosen layer; right-click clears it. Ground is the path level, Middle and Top are the two blocks above it. Gold outlines mark the path blocks each ring needs.

Each type is added up, then the square roots are summed. Spreading blocks across all seven types gives far more than stacking one.
Bonus steps
Between steps the bonus rises smoothly with tranquility, up to the cap set by your path rings.
