Good catch, I think you're right here wrt E hem projection impacting RMM in GEPS. RMM is identical w/ GEPS & GEFS but there's also more signal propagating to W Hem & the strongest -VP200 is deeper into CP on the GEPS. Obviously that's in large part due to aforementioned ET var. pic.twitter.com/2hdwQ3KUdm
