Modern oil filers have anti drain back check valves. Even my 1937 Ford would produce oil pressure in 5 seconds cranking at 100 RPM with the original 6 volt starter which was direct drive, or you could crank it by hand!
Oil pressure is produced virtually instantly, long before the gauge reads oil pressure. in probably twenty revolutions of the engine, maybe less. If your windows are clear drive away immediately after starting the engine. By the time you have it in gear you have max oil pressure especially in a cold engine. In fact the pressure relief valve is already dumping excess oil pressure.
