[PD] Refactoring a PD patch

It's impossible to prescribe any certain way to patch, it's a bit of an art
and very personal, but I have established a kind of pattern that I seem to
follow and always try to tidy up patches into this form. This is mainly for
DSP, synthesis and effects...
Any inlets lined up along the top. Signal to the left, control to the right.
Input preconditioners, max, min, clip, >=, == etc
Scales and offsets all lined up
Any [receive] or [delread] that form part of a loop within the patch need to
come out near the top
Then, however many parallel sets of:
All intermediate variable calculations, cutoffs, filter coeffs, converting
periods to freq, midi to freq etc
Primary signal sources, noise, phasor, osc
Output conditioners, limiters, volume, DC traps etc
Things with cohesive function are clustered together
Things that feed back or to side chains are offset sideways
No patch cords ever run on top of each other
Avoid cords passing over another inlet en route to destination
Fan outs 1:n greater than 3 are arranged symmetrically around a vertical center
Fan ins n:1 (n>3) the same
How you can parse the file and identify any of this is a damn hard problem imho.
