The asymptotic scaling conjecture for the volume loss function

For L,R>0L,R>0, let

VL(L,R):=inf{Vol(E(Φ)):Φ ⁣:B4(πR2)R4 is a symplectic embedding with Lipschitz constant at most L},\mathrm{VL}(L,R):=\inf\left\{\operatorname{Vol}({E}(\Phi)): \Phi\colon B^{4}(\pi R^2)\to\mathbb{R}^4\text{ is a symplectic embedding with Lipschitz constant at most }L\right\},

where

E(Φ)=Φ1(R4Z4(π)).{E}(\Phi)=\Phi^{-1}(\mathbb{R}^{4}\setminus Z^{4}(\pi)).

Volume-loss scaling conjecture. For any ,r>0\ell,r>0, the limit

limRlimLVL(L,rR)VL(L,R)\lim_{R\rightarrow\infty}\lim_{L\rightarrow\infty}\frac{\mathrm{VL}(\ell L,rR)}{\mathrm{VL}(L,R)}

exists and is positive. This conjecture concerns the relation between the known upper and lower bounds for volume loss and the asymptotic dependence on the Lipschitz and radius parameters; the supplied text gives no resolution.
