By default, the short/long year option is not checked on the fixed assets calendar for a year. It is suggested that by default, the option be checked and with the depreciation percent set to 100%.

While most customers are likely on monthly calendars, those that are not and use periods that vary can be severely and unexpectedly impacted based on the algorithm used. For a calendar year that overlaps slightly from the prior and next calendar year, this approach results in 116.67% depreciation.

It is obscure option, and defaulting to the approach that would handle the most customers correctly, this would eliminate what is likely a recurring issue for support and disruption. And the overall calculation logic would not need to be changed.
