beyond this limit.  Identify the cause and correct.  Repeat these readings using the same appraiser and unit as originally used or
discard values and re-average and recompute R and the limiting value from the remaining observations.														For information on the theory and constants used in the form see MSA Reference Manual, Fourth edition.

你重复数太多了
