My G50UH service manual says this in the notes of blower performance data: Also see Filter Air Resistance table.
Which means if you place the probe before the filter as they show in your picture, you still need to account for the PD of the filter based on the Filter Air Resistance chart in the manual.
Either way works.
Instead of learning the tricks of the trade, learn the trade.
