Thanks for playing! Yes, most of the item weights are as close to legitimate as possible though I didn't personally weigh anything myself. Instead, if I could, for items like the desk phone, I went on Amazon and found the closest looking product to the model I was using in game and used the item weight from the listing. For others, such as the football or the guitars, I did a simple Google search and checked to see what the range of weights given was and then picked one from within there. Only a few items did I just assign a weight I thought was correct, such as the clay pot where those kind of items can be any size.
