No I think you are right .To my mind, unless your plough and track widths perfectly match to put the middle of the working width (furrow wall to rear landside) in the middle of the tractor, then the offset would need to be swapped L to R each pass.
But, like my GPS, my mind is simple at times.
If on top. It’s easy. No offsets needed . ( you don’t need them either if you plough in furrow )Sorry I forgot to mention we will be ontop.
I do 95% of my in furrow ploughing with rtk autosteer. You just need to mess about with implement width sometimes. I've a small offset in mine for some reason too. My ploughing wouldn't win any awards. Its fantastic for marking fields out and finishing.
I have exactly the same problem with our LO 85 ploughing onland, for some reason the plough pulls slightly wider with the right hand bodies so have to use an offset (which will vary with soil type) to overcome the issue!I believe your offset is for a different purpose from that discussed earlier on. One cannot apply the offset that describes how the plough coverage centre differs from the centre of the tractor. This would not work because this offset would be different depending which way the plough is turned.
Perhaps you have the same issue as I have with our Kverneland plough. For some odd reason our plough follows the tractor with a bit different offset (ignoring the left/right direction, just centre of tractor to centre of plough) when turned left compared to that when turned to right. I feel this should not happen but it still is there. Not a big difference but noticeable enough and can be fixed with a small implement offset setting.

It's 7 furrows so is it as simple as 7x 16" or is it better to do a run and measure what you have turned over? And were would you take your front too back measurement meaning from drawbar to middle of the plough or the land wheel?
