RHY.2:5.2 - A contact trace leaves out the load change

A constructed dance recording shows a foot contacting the floor before a transfer becomes usable by the partner. For a question about foot placement, contact timing may be enough. For a question about responding to the transfer, the account also needs the load change and the partner’s response.

Select those relations from an appropriate observation or bounded trial. If the video cannot show them, return the unresolved relation rather than labeling the contact “weight arrival.” RHY.4 develops the timing comparison.
