dude with fragmented backups

[roterdam]

i'm doing few tries with armory fragmented backups 3 of 5 .
when i'm restoring from 3 fragments seeds random of 5 , i see that if last letter of one seed it's wrong the wallet is restored well .
i'm thinking possibly information in this fragment are redundant?
if it is ok , how redundant is this?

thanks in advance to all users could help me!!

It can fix a single byte error. Data is served as 16 bytes packets with 2 bytes checksum, which is the first 2 bytes of the data's hash digest (sha256). If the checksum fails it will try all of the 16 bytes (one at a time) with all 256 values in hope of hitting the expected value.
