It's fairly simple...
No matter where you fly, if you want to claim time towards a JAR-FCL licence, log your actual flight time in accordance with JAR-FCL requirements. Which you can find in LASORS.
If you want to claim time towards an FAA licence, log your actual flight time in accordance with the relevant Yank document.
Anything else will be an expensive mistake!
Logging 'standard block times' is probably some trick dreamed up by accountants. And it's UTTER bolleaux which would invalidate your personal flying logbook outside the third world.
