Not sure why you would think the percentages would be the same for a break even point? The copper/steel ratio may be the same, as this is really a function of transformer type and various transformers may yield various copper/steel ratios. None of this has to do with your break even point. The math is correct.

You would have to elaborate the rest of your post. My statistics is very solid as my graduate studies were in probability and econometrics but I'm not sure why you would want to incorporate a dimensionaliss variable like pi into a model about weight
