Nismo Oil Change

No I did not roll it off the ramps to drain. How would I be able to put the drain plug back in. I used a tempo fluid extractor, stuck it in the oil dipstick tube and drained out almost a quart. Now it sits dead even in the middle of the 2 indicators on the dipstick. When I do oil changes on my bike I am always having to put less than the capacity because of the residuals that sit in the engine. but come to think of it, when I do oil changes on my other cars I put back in the required capacity and it sits in the middle of the indicators. I've checked it 4 times after 15mins and its dead on where it should be now. But its just weird how I put in 5 quarts and had to drain out almost a 1 quart when the capacity is 5.2 quarts. I used Royal Purple and a Royal Purple oil filter, which is a little smaller than the factory one.
