I guess it can be hard to find the right numbers from NumisMaster matching to coins in Numista without #km.
But the robot could verify the current list of NumisMaster km# and inform the referee if any new numbers appeared for specified issuer. This kind of list of newly added km# will faciliate a lot for manual update km# in Numista.
And yes, NumisMaster was updated recently, I noticed this mid-October by hasard when I wanted to check something for Alderney. I entered something in search and some newly added coins appeared on the list. It take me 2 evenings to add all new Alderney km# (I don't count but maybe 40 entries). What is more, some older coins were updated to reflect the rule CuNi is km#XX, silver km#XXa etc. It was done for 2004-2006 coins from Age of Steam series where previously some silver versions were listed.
So list of update generated by robot could be not only new km# but also km# changes.
