Paul, thank you very much for sharing this. Glad this is of interest. And Phil was right – CG Dra went into outburst the following day. I couldn’t capture the whole night as ACP crashed, but here’s the curve from tonight, 28th.

Eclipses No(s): 29,30
State: Rising
Data Quality: Very good (check star sigma = 0.022)

Two U-shape/Low hump/Symmetric (U/L/S) eclipses, expected at this state. Bright spot ~ 0.08 mag amplitude – close to normal asymmetric eclipse mode, but this signifies the accretion disk is getting brighter. Mild flickering throughout, although there’s a prominent small hump at the minimum – likely the flickering source is not eclipsed – inner accretion disk or bright spot extending? Some egress standstill on the first eclipse.
