It was always by guess and by God. 15 second update on the radar, if you turned on the sweep you rolled out in front, if you waited till the next you rolled out 6-8 miles behind. Give it a squint, wait for a few seconds and use urinology to order the turn - and hope he rolled straight in and didn't say, "say again". If it worked it was superior pilot skill, if it didn't it was the controller's fault...
But, as I told Porkie when he complained after I rolled him out ahead of the last pair in a low level 6-ship, "You f*cked up - you trusted me.."
