highmatergogo I've done the 3 K-Ceptor spinal tests, and they were mostly responsive, accurate, and free of drift. I've also performed the spine & legs tests, and while the sensors maintained good responsiveness, drift and incorrect limb bending was an issue, as well as somewhat inaccurate spine positions (which may be due to the K-Ceptors defining direction a little bit differently than my compass).
However, I have yet to perform the full spine test, as recent test cube evaluations show drifts of varying speeds in all my K-Ceptors, despite having calibrated them relatively recently. I'm waiting for further instructions/software updates/the new 2.8 add-on in the meantime.
One thing I didn't know you could do though, is disconnect a branch of sensors during a test and still maintain functionality for the rest of the rig. I'll try that and see if it affects my drift and lag the next time I run a full body test.
Also, I don't know if this will affect anything, but my new Windows workstation laptop will be arriving in the next day or two (I'll FINALLY be able to use EEVEE!), so if needed I'll be able to perform tests on both Mac and Windows computers.
