Google what "semantics" mean. But go ahead and try to explain the meaning of the words "shortfall/deficit/loss" by using math. Good luck. You cannot explain your mathematical findings without "using" language.
China cannot account for (for example) 105% of a loss. That 5% is money, they have NOT LOST because they've made more than expected elsewhere.
Same paradoxon with the "more than 100% of the profits". You cannot take more than the entire profit that an industry makes. If the others lose money, they have made no profit. A profit is by definition a financial gain. A loss is not a negative profit, a loss is no profit at all, because there is no gain.
Fascinating how long you need to realize that I never doubted the math, but your choice of words.
