I think the best option for your team would be to look at whether or not the center of mass offset provided by moving the tote inside your frame is worth the extra work based on your strategy. If you want it to be that much harder for you to tip over, then go for it! Otherwise, you might be better off allocating your resources elsewhere. There is no "incorrect" way of completing this challenge (unless it violates the rules.)
