Session-relative movement evidence: the athlete’s repeating pattern in this clip, the strokes that meaningfully depart from it, and the evidence behind the read. ErgScreen does not grade every rower against one universal “perfect stroke.”
Trust and guardrails
One clip can reveal a useful question. It should not pretend to answer every one.
ErgScreen is built to make the next conversation clearer — while keeping measurement confidence, uncertainty, and the final decision separate.
It helps athletes understand what their video may be showing, gives families a cleaner way to share context, and gives coaches evidence they can review without replacing their eye, standards, or on-water judgment.
The ErgScreen position
Make the evidence visible. Keep the decision human.
Watts and splits matter. The boat matters most. ErgScreen sits in between: it organizes the movement layer rowing often sees too late — how the stroke held together, what started to change, and which strokes support the read.
The goal is not certainty. The goal is a better next step.
Athletes, families, and coaches can discuss the same evidence instead of guessing from a loose clip.
The report surfaces signal and uncertainty. The coach still decides what matters and what needs verification.
Two different kinds of confidence
A clear measurement is not automatically a complete decision.
ErgScreen separates confidence in what the clip measured from confidence in the larger question a coach or family may be asking.
Framing, visibility, frame rate, rail alignment, stroke boundaries, and signal support determine whether a category can carry the report. Not every detected stroke automatically becomes evidence: the usable sample is qualified, and omitted strokes remain visible in the evidence base.
Fatigue, another rate, response to a coaching cue, repeat-session consistency, and on-water transfer require evidence beyond one short clip.
Clear measurement does not become false certainty.
How the evidence stays bounded
The report should say only what the clip can support.
ErgScreen is designed to keep observation, interpretation, and larger rowing conclusions separate.
ErgScreen establishes a usable comparison sample and can omit strokes that should not contribute to the read. Stroke Evidence preserves what counted, what was omitted, and which strokes supported each qualifying finding.
ErgScreen can identify when visible movement relationships change within the clip. It does not claim to know why they changed unless the available evidence supports that conclusion.
ErgScreen evaluates visible two-dimensional movement relationships in the submitted side-on clip. It does not directly measure force, left-right symmetry, injury risk, or three-dimensional body mechanics.
When the video cannot support a conclusion, ErgScreen should not make one.
Unknown is not negative
Missing evidence stays missing until it is tested.
A short side-on video may answer one question well and leave several others unresolved. ErgScreen does not turn an untested domain into a clean result or a negative judgment.

One clip can identify a question worth following. It should not reduce an athlete to that question.
What ErgScreen does not claim
Clear boundaries protect athletes, families, and coaches.
ErgScreen supports better review. It does not make promises that rowing evidence cannot responsibly make.
A polished packet can make evidence easier to review. Recruiting decisions remain with programs and coaches.
ErgScreen can show what the video supports. The water still gives the final answer.
Lineup Optionality can apply different coach-selected role screens to supported ErgScreen evidence. Meeting a screen is not a seat assignment or a prediction of on-water suitability; the coach still decides who belongs in the boat conversation.
They give the coach a cleaner evidence object to interpret, challenge, verify, or set aside.
Across multiple ErgScreens, Coach Intelligence compares supported findings across sessions. It does not treat independently recorded videos as one continuous geometric measurement.
How to use it responsibly
Use ErgScreen to move from guesswork to better questions.
The strongest use is not “this report says yes or no.” The strongest use is knowing what deserves attention, what needs context, and what should be verified before the next decision gets smaller.
Use the screen to see where the stroke looks strong, where it changes, and what context should travel with the clip.
A Recruit Packet can make the submission more polished and easier to review. It should not be treated as a guarantee.
Review the signal, look at uncertainty, verify what matters, and keep the final decision anchored in your standards.
The simple rule
ErgScreen can improve the next decision. It should not impersonate the final one.
Screening, not selection.
The best use of ErgScreen is to make evidence visible sooner: what looks worth reviewing, what remains untested, and which follow-up would clarify the question next.
