No Matt. Decocker models with or without a safety must start decocked or, at the shooters option, hammer down by rule in SSP. I don't know of anyone who chooses the latter as in doing so it lengthens the trigger pull.
For SSP they cannot start with the hammer fully cocked.
For decocker models without a safety they must start either decocked or hammer down in ESP. DA/SA guns as you know start in SSP with the hammer fully down.
See page 19 2 B for SSP requirements. The rule covering the balance of the pistol divisions falls to page 10, C 15.
The Para LDA's hammer falls at rest fully down when partially cocked.
Clarity and Vague are strangers when it comes to this issue but our rule book is what it is. Hopefully the next full revision of the book will clear these questions up.
Take Care
