Partial requests kept all fixed phase commands and changed packet cost in seven SEEG rest recordings

A six bit message with requests for eight exact voltage means first kept all 94,080 fixed phase decisions in seven public SEEG rest recordings. The method saved 46.75% of bits with no message headers. Requests for all 50 means saved 29.21%. Extra requests increased link delay. These results apply to a fixed 50 ms theta reader, reliable messages, and the stated packet format. They do not show better phase accuracy or stimulation benefit.

usesExact bounds saved 17.7% of pair calculations and kept all full reader decisions in eight SEEG recordings with clipped pair scores
Its partial exact voltage requests for phase commands informed the related-method comparison. This study tests a fixed-order subset optimizer and lazy pair power calculations. No code or data were copied from it.

usesPhase updates saved 20.17% of bytes and kept receiver forecasts within 10 degrees of local forecasts in seven SEEG rest replays with no link loss or delay
Its partial voltage-feature request test informed the related-work comparison. We instead studied temporal phase-output corrections and a bounded phase difference. No code, voltage input, or outcomes were copied from this publication.
