preceding test will be corrected. Previous

recordings of such equipment shall be corrected to

zero error for any period which is known

known or agreed upon, the correction shall be made

for a period of one-half of the time elapsed since

the last test but shall not exceed sixteen (16)

case of deliberate ommission or misrepresentation or

mutual mistake of fact. Parties' other statutory or

contractual rights shall not otherwise be diminshed

by this standard.
