28K numbers were actually used in 1979. The sequence was not always consistent, so you can't just extrapolate how many might have been used in a given year.
For example, 26K through 34K were used in 1979, but 35K through 44K were actually issued in 1978.
The SCSW just gives estimates and ranges, so the numbers are roughly correct.
