Don't get bogged down in the weeds here. Realistically, with only two miles to analyze, the

bogey will not drift at all, drift only one degree, or drift really fast. Applying headwork, one

isolated degree of drift can realistically relate to 0.5/nm. If the bogey is off to the races,

1-2 degrees/nm will be call for a large TA adjustment by at lest 20.
