As for the water bottle vs. rotating weight, I noted that as well. Which is why I compared dropping 100-200g of rotating weight (tires) to dropping a 500-750mL water bottle. It is a very rough comparison, I haven’t ever done the math to figure out how close they are, but I suspect it is close enough. Even 200g of rotating weight isn’t THAT significant when you consider the likelihood your pair of wheels weigh 2500g+ (assuming low end box wheels since we are discussing wire beads).
