Agree 100% with both comments - for interest the Pilot's Notes General, which were always issued and used in conjunction with the Pilot's Notes, say this about g forces and blackout thresholds:
I remember reading somewhere that 109 pilots had slightly higher blackout thresholds because their seats had a greater backward angle than the British - RAF fighters later adopted two-step rudder pedals for similar reasons.
