Same here. While attending USAF test pilot school we took a trip to a new simulator. One of the instructors and I flew against each other (we actually had both been in the same squadron at RAF Lakenheath).
The set up was basically a fly out to 20 nm separation then turn in. First to get radar lock could shoot BVR. So the instructor kept his speed up to around 450 kts for the turn-in. I decided that the game was to complete the turn the quickest so I flew at 275 kts (not a very good speed for real combat). After I got missile kills on the first three engagements I finally revealed my “secret” tactic.
