Why is this better? Because it solves the silent killer of power electronics: IR drop disguised as component failure . In Rev 15, a technician might replace a perfectly good MOSFET thinking it was faulty, when in reality the copper trace was acting as a resistor. Rev 20’s layout turns the PCB into a proper bus bar.

He plugged in the DC jack. No amber blink. A solid, steady white light breathed on the edge of the chassis. He hit the power button. Rev 20’s layout turns the PCB into a proper bus bar

The Revision 19 schematic Elias had been working from was functional, but it was a victim of "digital clutter." The grounding paths were ambiguous, drawn in a way that suggested the layout engineer had struggled to fit the traces onto the board. The signal lines for the current sensing op-amps ran parallel to the high-voltage switching lines—a classic recipe for noise injection. In the PDF, the lines were drawn on top of each other, obscuring the interference.
