Now, it is easy to check whether $\frac{L}{l} \geq \frac{\piup}{2}$ (equation \ref{lfR2}) in which case it is equally easy to calculate $R = l$. Our attempts to write equation \ref{lfR1} in the form $R = f(l, L)$, however, have failed. Still, we can work this relationship out numerically (figure \ref{lfRfl}).
The combination of the projected length of a film that only curves in the $\vec{y}\vec{z}$-plane (i.e.\ not `sideways') and its radius of curvature is unique (figure \ref{lfRfl}). This allows us to calculate the radius of curvature from the \textsl{projected} film length $l$. This is not the case for the actual film \textsl{tip} position: different radii of curvature may result in the same film tip position (figure \ref{figcurllnR}, green)

\noindent In the example that we choose to show you, fancy estimation \textsl{rocks}, big time. Of course.
But in all honesty, we had to actively look for this impressive example. If we had for instance chosen to fit frame 2 \textsl{before} frame 1, the benefit of fancy estimation had been much less impressive. Likewise if the target length for frame 2 had been (much) closer to that of frame 1. Furthermore, the old adage that 'life is like a sewer -- what you get out of it depends on what you put into it.'\footnote{bagger in = bagger uit} \cite{Lehrer1960}, also holds for the estimation of the parameters of our analytical function. The quality of the fit, and therefore of the new estimate for $\sigma_x$ depends on the quality of the input values (estimates so far).

In general, the quality of the fit will improve with more input estimates, and for input estimates that are equally spaced (no clustering of points). But it is impossible to predict beforehand how the fits are going to behave during the estimation process. And when the analytical fit is off, linear interpolation may actually be better than the `fancy' estimation.

Projected edge length only assesses curvature in 2D. For anisotropic constructs it therefore becomes a non-linear proxy for the actual cell traction stresses that deforms the construct in 3D. And because the predominant fibre orientation affects the amount of out-of-plane deformation, comparison of projected edge lengths between constructs can only be valid for (near) equal values of $\mu$.\\
But it gets worse.\\
\noindent Even for a given predominant fibre orientation $\mu$, projected edge length $\frac{l}{L}$ may not be unique for a given value of cell traction stress $\sigma_x$ (figure \ref{lfmu_sigma}). We found a minimum in the $\frac{l}{L}\left(\sigma_x\right)$ relationship \textsl{for more than half of our random models} (figure \ref{anispace_md_fig}). The measurement of $\frac{l}{L}$ is ambiguous around these minima.\warning

Our current analysis does not suffice to predict the occurrence or severity of these minima in terms of the \fiblab{} parameters $\mu$, $\sigma$, and $P$. Figure \ref{lfmu_sigma} suggests that the occurrence this minimum is most prevalent around a predominant orientation $\mu$ that is about 30\,\degree{} off-axis $\left(90\,\degree \pm 30\,\degree\right)$, but $\sigma$ and $P$ will also have their influence.\\
