you're right about the over precautious check calls whilst performing PAR approaches but remember, they're designed for Mil fast jet. The work load in a Harrier cockpit can be extremly high and checks such as "gear" have saved more than one ac. DH is asked because it varies between ac, cockpit checks are a form of speed control in the radar pattern e.g. early checks if you're catching the one ahead; Mil controllers can't specify speeds to fly in the RTC.
