Werner did not teach anything about the order you have to enter information. There are three things that need to be in the TDC, target speed, angle on the bow/course and range/bearing. It's very important when you turn on the position keeper and when you enter the information.
I always turn on the position keeper first. You can turn it on any time before the last input, but if you do it first you'll never forget it. Enter in this order: speed, AoB and always last, range/bearing. You'll instantly finding yourself hitting MOT (middle of target) like you intended!
