I think I understand your questions now. You have 2 tabby treadles....one is outside (the one on the left ) and one is inside (the one on the right). Then you have your 4 sets of pairs....Each set of those 2 treadles has an outside and an inside. But for your floats pairs (and it doesn't matter if they are warp floats, weft floats or lace) your right treadle of the pair it you outside and you right treadle of the pair is your inside. In all these options you are weaving, tabby, float, tabby, float, tabby. So if you are weaving lace...you weave 1,8,1,8,1 (outside tabby, outside pattern, outside tabby, outside pattern, outside tabby, and then you weave 2,7,2,7,2...and that is inside tabby, inside treadle of the pair. etc.
So when you look down at your treadles...if you have them marked in their pairs they way I do...with squares on on pair, circles on another pair, and stars on the other pair....you see those marks, (square, circle or star) and you can identify the pairs....and you automatically know that the outside one of the pair alternates with the outside tabby, and the inside treadle of the pair alternates with the inside tabby.
