As for recomended by the manufacturer.... Not sure how good that is
Here goes. The reason i ask is to see how many folks have noticed this and from the sounds of it... One has shown it in this thread.
Two things that effect static tiller...
1: Brace height: the higher the brace height the higher the tiller will show.
2: Limb pre load: The more the limbs are wound in the more tiller shows.
so how important is static tiller?
Although it is the only measurement you can take, its a very crude one.
If you have 4mm, or zero or any other measurement... of tiller and that is your holy grail, then adjusting it again from manufacturers recomendation could be a good thing, or worse a bad thing. The measurement you have taken is static tiller? Would you not say that 4mm wound out (our weight is measured fully out) and Brace height in mid position of recomended then that should have the same tiller difference, to that of a pair of limbs with a high brace height, fully wound in, even if they show 8mm. For example, isnt it the same difference in top to bottom limb, its just showing more ? The balance is till the same. What effect does on tiller have on accuracy? For example, your using a different part of the DFC if your limbs are wound in. but does the now 8mm have a effect, or should it be wound back to 4mm?
This came about again in a conversation with a fellow archer, thought we could open it up and see what you have observed too.
