Is there any way to tell the absolute amount of flow by looking at the flow meter? There is a legend on the gauge which reads 100 to 400 ml/min, but is that with what SC trimmer setting? If that's with 'centre' setting, how is the legend changed when SC is set to max?

Per your flow charts, four 0.3mm nozzles should flow enough (around 440 cc/min required with 20% ratio) compared to fuel flow (around 2200 cc/min) at the moment so there shouldn't be a need to change them. But of course if the actual flow is lower than what is calculated, it might be needed. But then the question is, why are the calculations wrong.
