It is redundant, so, depending on the type used, you may need to hit
up to %30 of the white spaces:

Level L	7% of codewords can be restored.
Level M	15% of codewords can be restored.
Level Q	25% of codewords can be restored.
Level H	30% of codewords can be restored.

Probably better to just hit it all.
