TOOL 02 · OBSERVATIONS, NOT ASSUMPTIONS

How fast is your factory, really?

Time a stable sample, enter the amount processed and estimate the remaining work. This predicts hay processing, not needle discovery.

YOUR MEASURED SAMPLE

Make the numbers comparable.

Use one consistent in-game unit. Must be greater than zero.
Time a steady interval. Must be greater than zero.
Use the same unit as the sample. Zero is allowed.

Blank by default. The example is arithmetic only: it is not a tested machine or a recommended layout. Inputs are not saved or sent anywhere.

YOUR RESULT

Start with a measured sample.

The result will show a per-minute rate and an estimated time for the remaining hay.

What the calculation means

Rate per minute = amount processed ÷ sample seconds × 60
Processing time = remaining hay ÷ amount processed × sample seconds

These equations assume a stable processing rate and no new input added to the remaining quantity. Stops, changed upgrades and bottlenecks can make the estimate inaccurate. Repeat the sample after a meaningful factory change.

Use hay units consistently. Do not mix a count of finished bales with a count of raw strands unless you have independently established the conversion. The tool cannot infer that conversion.

Not a completion timer. Emptying the measured material is not proof that every needle was found or that an ending condition was satisfied.
