 We will call our repeated measurement of $tilde(x)$ that is subject to a certain error $tilde(x^*)$.
 To perform reconstruction with $tilde(x^*)$, we will first need to find all $S$ quantizers for which we generated the helper data in the previous step.

+If $S$ is even, we need to define $S$ quantizers offset by some distance $phi$.
 We can define the ideal position for the quantizer bounds based on its corresponding metric as centered around the center of the related metric.
 
 We can find these new bounds graphically as depicted in @fig:smhd_find_bound_graph. We first determine the x-values of the centers of a metric (here M1, as shown with the arrows). We can then place the quantizer steps with step size $Delta$ (@eq:delta) evenly spaced around these points.

 //This is also shown in @fig:smhd_2_2_reconstruction, as our quantizer curve is moved $1/16$ to the left and the right.
 In @fig:smhd_2_2_reconstruction, the two metric indices $i = plus.minus 1$ will be multiplied with $Phi$, yielding two quantizers, one moved $1/16$ to the left and one moved $1/16$ to the right.

 As previously stated, we will need to move the enrollment quantizer $s/2$ times to the left and $s/2$ times to the right. 
 For example, setting parameter $s$ to $4$ means we will need to move the enrollment quantizer $lr(s/2 mid(|))_(s=4) = 2$ times to the left and right. 
 As we can see in @fig:4_2_offsets, $phi$ for the indices $i = plus.minus 2$ are identical to the offsets of a 2-bit 2-metric configuration.
