Eventually it would drop down to say 20-30 psi at idle, but then rise to 60-70 psi when you blip the throttle. I don't remember the exact pressure but that's not the point. Why would you want it buffered? A true enthusiast wants to know exactly what's happening when it happens.

The buffered gauges are the same, but the accumulation is over a few seconds so the gauge doesn't sit there and bounce around.
You are not calibrating or diagnosing anything. You don't need instantaneous pressure readings other than to make yourself look cool. To me it is just shit moving around that I don't need to see. Let me know when the oil pressure drops below a level that will do damage to lower end bearings. That is really all I need to know.
