  We present all two-loop five-parton leading-colour finite remainders in the
spinor-helicity formalism by analysing numerical evaluations of their known
expressions in terms of Mandelstam invariants. Recasting them in terms of
spinor-helicity variables allows us to obtain expressions which are more
compact, faster to evaluate, numerically more stable and manifestly free from
poles of higher order than necessary. At the same time, due to the better
scaling of our reconstruction strategy with the complexity of the input, we
required one order of magnitude fewer numerical samples to complete the
analytical reconstruction than were needed by the authors of Ref.
\cite{Abreu:2019odu}, albeit using higher numerical working precision. This
places our reconstruction technique as an alternative to the finite-field
single-numerator reconstruction for future applications.
