I don’t use the center stand, so I have a mirror that is placed to the side of my bike. Since they say you need to check the level while it is hot, I check my sight glass in the mirror (while the bike is level) after letting everything drain (5 min?). What you might try is to check the sight glass while it is hot as a reference point (full), then let the engine cool overnight. Then when the engine is cold and level, check where the level is when it’s cold.
