what rates of break wear are reasonable on a vauxhall insignia

Car serviced in Oct 2011 with front pads reported as 25% worn rear pads 10% worn. This was at 15,763 miles. Now at 22,658miles front pads are 70%worn and rear needs new discs and pads. Is this reasonable.
It can happen. The front pads clean overnight corrosion off the discs, but since 95% of braking is on the front, the rear pads are not as effective in cleaning off corrosion. That's why corrosion eats into rear discs first.
