What this part means

the depend on a joint choice of.

Its job in the formula

epsilon is a part of this expression. Its role is fixed by the surrounding article and by the operations shown in the formula.

Where the article explains it

It does, however, depend on a joint choice of ϵ\epsilon and δ\delta that this article has no privileged way to fix, and for a sufficiently coarse compass paired with a sufficiently strict qubit fidelity, the ordering in the title simply does not hold.

The passage around this formula

…— both thresholds are built from the same radiation, collected by the same observer, under the same scrambling dynamics — so it is not a decoder artifact in that sense. It does, however, depend on a joint choice of ϵ\epsilon and δ\delta that this article has no privileged way to fix, and for a sufficiently coarse compass paired with a sufficiently strict qubit fidelity, the ordering in the title simply does not hold. The correct statement is conditional: for comparably stringent, no-external-frame tolerances on…
