Merlin HC4 - SHOL Increases
Ship Helicopter Operating Limits for Merlin HC4 expanded significantly after trials allowing increased payload and endurance.
Extensive trials extend range – or payload – of Royal Marines’ Merlins (mod.uk)

"For nearly a decade, the ‘handbook’ for safe Merlin operations – such as weight limits, wind speeds, humidity, weather conditions – known as Ship Helicopter Operating Limits or SHOL have largely been based on data gathered using the helicopter’s predecessor, the venerable Sea King: older, smaller, lighter."

To some extent the new SHOLs will also be based on other types performance, as unless they do a trial to each ship class there'll be read across based on whatever type did the most comprehensive trial on that ship, e.g. Wildcat to T45.
From the OP's link
I don't think there is anything 'artificial' about the operating weight increase when you load it with ballast!
The Merlin was also fitted with ballast which was incrementally increased to artificially increase the aircraft’s operating weight.
