Thanks for posting Gavin’s vids et al. Agree ground is not wet in earlier NYE, then raining around midnight.
Based on that, disregard any EMB and WW exclusions.
I would still say that the PICCADILLY and RED BUS dates mentioned are not based on lingering damp conditions but are rather based on the fact that our suspected times when those pics were taken (RED BUS in afternoon and PICCADILLY at or near sunset which was approx 3:50pm) are bracketed during hours of measured rain. Not after, but during hours of rain.
What about the WW bulbs and rain and closed dates? Did anon want to make a summary report on that digs results for possibly excluded dates? To include dates bulbs are decidedly not matched to the Wild Maus pic, missing light bars, etc.
