1911 deleted entries at findmypast, now available at Ancestry

I wrote earlier about findmypast's contra-common sense approach in deleting people who were entered in the census, but then 'crossed out'.  Sometimes this is the sad misunderstanding of parents including long-dead children.  More often this could be nurses called out in the middle of the night to go and look after a patient or sons out fishing.  I'd like to hear if any lifeboats were called out on the night of 31 March 1911, whether those brave men are recorded in this census transcription at all.  I felt sure that Ancestry's more dogged approach, like a row of combine harvesters coming at ya, would be sure to pick up these 'crossed out' entries, rather than letting its prey escape on such flimsy terms.  Sure enough here is Robert Henderson, appearing nowhere else in 1911 except on Ancestry's index.  I'm sure there will be many more.  Perhaps even my own grandfather, still not located!
