HP Cock is absolutely correct. The entire purpose of a "Gate" is to make sure you have enough height to complete your intended manoeuvre. It is absolutely fundamental to the continued survival of a LL aerobatic pilot. You MUST make your gate which you have adjusted for airfield elevation and weather. If you don't make it, you must have another plan in place in order to continue your display. Everything else is just noise. If you forget to check (??) then you go to plan "B". You must not carry on regardless.
