A battery's rated cycles start at 600, rise by 15%, then fall by 10%. Which calculation does NOT apply the successive-multiplier method correctly?

Explicación

The correct chain is 600 × 1.15 × 0.90 = 621, because the 10% fall acts after the rise. Using 600 × 1.05 = 630 merely adds the signed rates and loses the interaction between the changes.
