Kit
9 ft #4 rod, floating line, 12 ft tapered leader to 4–5 lb fluoro tippet.

What would change the calculation
Cooler water — back toward the 10–16 °C ideal band — would lift the score and ease welfare.
A drop and clear would lift the flow and clarity scores.
The dawn and dusk windows score higher than the midday lull.
