Difficulty interpreting the correct inputs for this template based on the latest version of the log file. Two possible interpretations;

Generally the sheet relates to claims incurred amounts, and the issue is claims incurred during accounting year (profit and loss type figures) vs cumulative claims incurred amounts (actuarial incurred triangle, latest diagonal figure). The first interpretation appears difficult to work with as there is no advice in the log file on how one would account for negative movements on the excel template. It also seems less informative in terms of providing valuable overall claims experience information.

We would appreciate feedback on the above, and any further commentary on this particular log file that would make the correct interpretation clear to us.
