a CEA for a reporting period must be worked out between the first estimation event in the CEA and the last estimation event in the reporting period for a CEA. The difference is conservatively estimated by applying a specified probability of exceedance estimation based on the difference between the mean of the soil organic carbon stock at the first estimation event and the mean of the soil organic carbon stock at the last estimation event in the reporting period. The probability of exceedance approach uses the variance of each estimate and its degrees of freedom (based on the number of samples taken), and a statistical confidence level set out in the Supplement (alpha value for the students t-test) to ensure the estimate of the change that has occurred in the CEA is conservative.
      If a project proponent uses model-only or model-assisted estimates to calculate the change in soil organic carbon stock for a CEA for a reporting period, then Schedule 1 cannot be used to calculate that amount for the CEA for any subsequent reporting period.
