I agree completely. Those old microfilm records are hard to read even if you know what you are looking for. I create records that may be used by researchers in the next century and I print everything - even so, I am sure that some future genealogist will puzzle over my "scratchings". I am also acutely aware of how errors can be made in the original records.
I will continue to search in the 1911 census. and will let you know if I find them.
It is my busy time of the year so I won't be doing much more this week-end.
I tried to post this yesterday but it bounced!
