# Layout accuracy is not the same as time saved

A useful field trial measures the path from an approved model to accepted marks—not just printer speed.

## Keep the claim and the measurement separate

Dusty publishes a 1/16-inch accuracy specification for its FieldPrinter. That is a vendor specification, not our field measurement. It also is not a promise about how quickly your crew will complete a floor. The buying question is whether the complete workflow produces acceptable marks with less total effort under your conditions.

## Choose the denominator before the demo

An illustrative trial might use accepted layout points or accepted square feet. Choose one unit that your team can inspect consistently. Count rejected marks, missing marks, and reruns. Reporting only completed print area can hide correction work, just as reporting only movement time can hide setup. Keep the output definition identical for the manual and robotic runs.

## Include preparation that disappears in a video

The vendor’s pre-print checklist calls for prepared files, site control, a clear printing area, and trained operators. Assign a person and a timer to those tasks. If file preparation happens in the office the previous afternoon, it still belongs in the workload. Record which work is a one-time learning cost and which repeats on every floor.

## Compare matched conditions

Use comparable areas, complexity, and acceptance tolerances. Log interruptions from other trades instead of quietly removing them from one side of the comparison. If the operator is a vendor specialist, state that in the result. A successful expert-led demo can justify a second trial with your crew; it does not establish your team’s repeatable production rate.

## Review worksheet

- Define accepted output and who inspects it.
- Record preparation, setup, run time, and corrections separately.
- Repeat with your crew before extrapolating to the project.
