I have had success when I

Run ahead of the convoy outside the DD detection range, ending at a point about 10-15 miles ahead depending on convoy speed, 90 degrees from the course line, about 1000-3000 yds from the target's course.
- The distance from course line depends on how accurate the computed course line is - closer with higher confidence
Monitor the convoy course and refine the target course track with sonar or radar plots
As the DD gets to within 5-6 miles, rig for silent running, dive below the thermal layer
Set torpedo speed and depth, select torpedo to fire
When the lead DD is about to cross the bow, begin ascent to just above 100 ft, call crew to battle stations
When above 100 ft, open outer doors
Rise to periscope depth, select target sequence for simultaneous impacts
Time and conditions permitting/warranted, close distance to 1000 yd
Fire away!
