Hi Folks
Assuming that the nocking point is adjusted to be the same for each verta-tune position - Is there a rule of thumb for the tiller effect on a bow with the different verta-tune positions? ie high verta-tune requires more or less tiller for the same dynamic outcome?
The vertatune system will lift or lower the 'centeline' of the arrow in relation to the vertical centre of the bow - so the will be slightly 'more bow' above or below the arrow depending on the height of the rest-nocking point line.
it's only 1/8 inch above or below the middle (normal) verta-tune position - so maybe it's not worth considering in practice - but just in theory..... the tiller must also change slightly - but in what way?
my guess is that the higher the rest - the more power will come from the top limb - this is the same as increasing weight on the top limb ---- so raising the verta-tune will effectively reduce the (positive) tiller 'equivalent'?
does that sound right?
and lastly - might it be significant from a pure tuning theory perspective? (ignoring whether the archer is accomplished or not)
cheers
