You shouldn't take the numbers in the console too seriously. Most of them are
calculated with rounding to cylinders in mind. Since most modern harddisks have
a cylindersize of 8 MB, the number passed to the filesystem during resize is
usually 8 MB smaller then you'd expect.

All this is done to prevent the filesystem from being larger then the actual
partition. But don't you worry, after the resize the filesystem is growed to
fit _exactly_ in the partition.

So a typical shrink would require the following steps:
- shrink the filesystem (make sure it's smaller then the partition)
- shrink the partition
- regrow the filesystem to fit exactly in the partition

I hope this makes it a bit more clear to you.

Please let me know if you don't understand something or if i misunderstood you
somehow ;)
