PROJECTED-KEYBOARD TYPING TRIAL
Purpose: Compare your own input methods on the same practical task. This is not a standardized benchmark or a published product performance result.
Use expendable text in a simple editor. Practice first using a different passage. Stop if uncomfortable.

Final text saved at:
Completed words/minute = passage words / (seconds / 60):

ILLUSTRATIVE ARITHMETIC ONLY
100 words / (150 seconds / 60) = 40 completed words/minute.
100 words / (240 seconds / 60) = 25 completed words/minute.
Keep accuracy beside speed. Alternate order across repeated trials to reduce practice effects. Never present these invented example values as measurements.

DECISION
Which task and setting worked reliably?
What remains awkward or untested?
Does surface/setup effort change the portability judgment?
Repeat with one changed condition at a time, following the model manual.
