I have had my square for just over a year, making one visit to just two plots in 2016, and two visits to five plots this year. It has taken me hours to input the data for this year and I have just been back in to upload photos of the plots from both visits. It is entirely possible that certain data have been wrongly entered! Could you include something on each page of the input forms that tells you what plot you are in and the date of the visit? Also I cannot change things on the first page so that one plot does not have a number and plot 5 is "Plot Plot 5" which is very annoying.
Maybe I'll find it a bit easier next year, although I may have forgotten by then the things I've learned this year. . .
