The increase itself doesn't matter where it starts, 10% each year over 13 years will always be an increase of ~245%.

It also matters a lot to look at the relative change no matter the absolute amount, since it indicates a trend. Even if the chance for something terrible is 1 in a billion, a steady 10% increase every year should worry everyone, since there is a clear trend (and compounding increases get big faster than you'd expect).
