hesela.devDVD PI Sum8
DVD PI Sum8 counts parity-inner rows containing errors over eight consecutive ECC blocks before correction.
The NIST studies describe a threshold of 280 PI errors in this eight-block window [1]. The denominator is not seconds, and the count is neither uncorrectable files nor CD BLER. Record the aggregation window with the value; an unspecified PI count cannot be compared reliably.
