The OP has a technique that after flare he waits till thrust comes up before reducing it to idle. As I posted before this incorrect and not supported in any document. With ATHR on when you flare you are supposed to close thrust and not wait till thrust comes up to maintain speed. It is the flare that is supposed to reduce ROD and not the thrust. If GS mini effect had increased Vapp then you may reach the flare height with idle thrust. Any aircraft can be landed with idle thrust if speed is high(within stabilized criteria). During flare if more thrust is required to reduce the sink then the approach is unstable and GA should be executed. And yes! Approach can become unstable even at flare height.
