I believe the correct way to check the oil level is this.
Start your engine and let it idle for a couple of minutes on the side stand.
Then kill the engine, count 30sec, to let the oil from the cylinder heads to drain into the pan, and lift the bike from the side stand. Hold it from the throttle's clip on so that it is ballanced on it's own gravity center. At that point you don't need much efford to keep it leveled so you carefully knee down and look through the oil window. Have the front brake lever pressed, during all this proceedure, for safety.
The oil should be in the middle between the min and max indicators (a bit lower or higher is not an issue). If "a bit" is not clear enough then take it as +/-1mm from the middle.
Always do this proceedure on a leveled surface (not up or downhill).
The service manual says 4.12 quarts with oil filter change and 3.9 quarts without the filter.
In my experience, on every bike I service I take the service manual's suggestions in mind cause the real indication is the dipstick or the window at the bottom line.
I remember the Cagiva Canyon that had a minus 200ml quantity indicated in it's service manual due to a factory's typing error and until the maufacturer issued a paper informing workshops on that mistake. lots of motorcycles where seriously damaged
