THE THING TO NOTICE
Reset practice is about examining a decision before the final contact or awkward entry. BerthLab records the path so you can return to a meaningful earlier moment without rewriting the original attempt.
Move the review point earlier
After an awkward result, inspect a frame before the last correction. Ask what information was already visible: orientation, remaining motion and the available room in the authored scene. The useful practice question is which decision you would change, not how to make the final frame look successful.
Use takeover without expecting a frozen boat
Takeover copies a recorded physical state into a new fragment. It preserves momentum and actual actuator state while setting the new propulsion target to neutral. It is not the same as restoring a paused checkpoint, which continues the same attempt and history.
Keep the outcome labels honest
A fragment does not complete an authored lesson. A clip from the middle of an attempt does not show its entire result. Shared video pages therefore label the attempt kind, source interval and reported outcome separately. Editing a title cannot turn an incomplete practice segment into a course completion.
Make the second run answer one question
Try an earlier reduction in propulsion, a different alignment decision or a fresh setup. Compare the resulting recorded paths using the same model and environment. Do not use a simulated recovery to justify continuing a risky real-world approach.
Source and limits
This note describes BerthLab’s versioned simulator and recorded-replay behavior, reviewed against the Pilot Edition source. It is not an independently validated on-water training method.
