From estimates to evidence

A useful starting point.
A reason to test.

A model helps you explore a question. Testing helps you understand what happens on your bike.

Tool outputs are estimates based on the inputs and model assumptions. Real riding introduces changing conditions, rider behaviour and other factors. Use the estimates to guide decisions and comparisons, rather than as a promised result.
