Fair enough.  If you're always fixing it soon afterwards it doesn't 
really matter much.

But in that case why not just go do it - why change the database first?  
If you tag the discrepancy you're only likely to attract somebody 
else's attention (which you don't actually want if you're definitely 
going to check it yourself soon - no point in both of you resurveying 
the same place straight away).

Regarding the last point: Are most of the incorrect entries not just a 
little bit wrong?  i.e. misspelt, but still better than missing data.

I see your argument about the relative likelihood of the two answers.  
I think replacing with OS would be better than temporarily removing the 
name entirely.  Something rankles about overriding the guy/gal who did 
a ground survey without going to the spot to check first though.
