I am reasonably well aware of the philosophy of the 175 design, including the absence of need to routinely look at the system gauges. A great concept, especially as when in the Sim I could set a system gauge to slowly creep into the red over many minutes and virtually no-one would notice until the warning light came on!
My only point is that when there IS an emergency, let's say a transmission oil issue, one would then I think want to monitor the gauge and thus a screen is lost from its normal function (providing PM with the same info as PF). So 99.999% of the time the concept is fine. For that 0.001% of the time when the crew are maxxed out with both an emergency and say an instrument approach, a 5th screen would have been better.
