It is interesting that on the Continent we do not see this sort of games to see what a son here, a daughter there, an aunt over here or a cousin furtherer away does. Only in the British situation I see this fetish on numbers and even then these are often quite discutable.
Where in the Netherlands or Spain the Court would simply say: The King and Queen bring a visit to city X or city Y, in the UK even a visit to the races is counted as "work" because Her Majesty accidentally has been requested to hand over a trophy, or to shake hands with the Chairman of the Wounded Jockeys Fund, or to have a little chat with a group leading a charity for retired race horses. Tick, tick, tick, tick: Her Never To Tire Majesty has carried out 4 engagements today!
Another example, the Courts of Luxembourg or Norway would describe: Today several Ambassadors were received at the Palace to hand over their letters of credence. No more, no less. In the UK: at Buckingham Palace Her Majesty has received the Ambassador of Jemen, followed by the Ambassadors of Tunesia and of Argentina. Tick, tick, tick! Three engaments added on the Queen's workload. The sad thing is that British media only orientate on these quite discutable statistics and compare the lazy Continentals to their "hardworking" Queen, while I have no doubt that the agendas of King Felipe VI or King Willem-Alexander are equally filled with engagements, visits, seminars, audiences, meetings and whatever.
