The documents listed below can be disregarded if discrepant only if the remaining evidence is sufficient to establish the DB. If a material element
(month, first or second day, or year) of the DB is reflected only in a document which
could otherwise be disregarded, the tolerance cannot be used.
There must be at least two separate documents which meet the criteria of GN 00302.115-GN 00302.118 unless otherwise specified in C. below.
Neither material discrepancy development nor a written determination is required when one of these tolerances is used.
