I was referring more to my date visited column which if I visit only I add date and don't move to the main spread sheet from the holding area, OCD creeping in here. Once I revisit with my mate it goes on the main list so when I filter I have to remember if I visited by myself this year/last year etc (hence the add a column to distinguish via another filter) and subtract numbers off the main filter and add to the revisit total. It then gets more complicated as the pubs I do outside the main area that both of us do are on different tabs and whether I add them at all which is the case with anything in the West Midlands so need to recall from memory or have a number of new pubs that day.
I don't make it simple for myself it seems...
