Because the compensation uses the actual observed counter values rather than an assumed latency model, variable queuing and arbitration delays that occur after the capture instant are automatically subtracted at the actuator.

That is the only concrete technical step beyond standard per-sensor processing and CAN messaging already common in agricultural electronics. The patent lays out the control flow cleanly and avoids obvious internal contradictions. Nothing else is demonstrated. No latency measurements, no jitter characterization under vibration or temperature swing, and no derivation showing that residual error stays inside the spatial tolerance set by nozzle spacing and speed. The stress-test concern therefore stands: the compensation step is asserted without evidence that it actually places spray where intended once real bus delays are present. Because the document is a patent application rather than a reported experiment, it contains no data, no code, and no falsifiable prediction. A reader looking for a working precision-agriculture controller will find the description suggestive but incomplete. A reader looking for a scientific result will find nothing to evaluate.
