The 2025 method does not have a specific method or recommendations for small catchments. In WINFAP 5.3, for catchments less than 25km2 the “Use ‘small catchment’ recommendations as default” is selected and disabled. As there is no specific small catchments method or recommendations associated with the 2025 method the standard 2025 method is applied.
This has been fixed in release 5.3.9411 which can be downloaded from here: WINFAP Downloads
