In c r codes, there are four levels of that error correction that are implemented. L is the lowest, restoring approximately seven % of data. C, for some reason, is the next up at 25% and h is the highest, at 30%. In practice, most c r codes seem to use m i guess they assume if more than 15 % of that sticker is damaged, you might as well get a new menu sticker.
