  "about": "Timing benchmarks (README: 'The timing benchmark'), chosen with battery.py timing --benchmark NAME: each set started from a model rugnux has to place by molecular replacement, timed per step and checked for a right answer. 'standard' needs only open data (the open arm's 9zlo, 9s02, 9gjx and 4nwv); 'inhouse' is the earlier set of two in-house standard proteins and 4nwv. 'start' is the model given to --model: an AlphaFold DB prediction committed in models/ (with its predicted aligned error beside it), or a deposited entry (committed in models/pdb/) moved by a fixed rigid-body transform (strict NCS expanded first, then x' = R (x - c) + c + t, R a rotation by 'deg' about the unit 'axis', c the centroid of the expanded asymmetric unit, t 'shift' in A). The reference model the placement is checked against is the one the battery itself uses for the set (its manifest row's 'model', else the PDB entry of the set id; committed in models/pdb/ for every set here but cytc_x10sa, whose reference_model.cif sits beside its data). 'expect': 'mr_sgno' the space group the placed model is in (the model decides the hand), 'rfree_max' the highest R_FREE accepted, 'cc_min' the lowest correlation of the placed model's intensities with the reference model's (shell-normalised, 10-4 A, best over the lattice's reindexing operators).",
