The Cybertruck Is a Disappointment Even to Cybertruck Superfans / Looking at the specs alone, the car is delivering 30 percent less range than expected for 30 percent more money::Looking at the specs alone, the car is delivering 30 percent less range than expected for 30 percent more money.

My guess is the author first calculated how much less range, in which case the bigger number is the denominator, then mistakenly did the same for how much more money, so (61k-40k)/61k ~= 30%
