Here's a hint for advanced users. Speed does not actually need to be zero. If speed is non zero and AOB *is* zero, and range is over like 1000 yards or whatever, this is still zero gyro in the TDC.

Why is this useful? I often attack convoys, striking 3 targets at once. Quite frequently, this involves one or two manually computed 0 gyro targets, quickly followed by one or or two targets handled by the TDC. In this situation, using the above leaves speed as one less thing I have to enter when I'm in a hurry.
