OMG - I've just made this thing again. I halved the recipe both times but it is so nice to have a carrot salad thats not saturated with mayo which means I can have as much as I want. I am going to try to get the recipe down to so many of each thing so I'm not weighing everything. I do have a 3Lb postal scale I use with my cooking that helps sometimes. It's self zeroing, meaning if you put a bowl with liquid on it it weighs the whole thing but if you put the bowl on before you turn it on it zeros out and just weighs what you pour into it.
