Is my filling time for the volume and alloy in my casting simulation accurate?

I believe I inputted the proper version but either way, I am doing casting simulations for a capstone project for my degree program and I believe that my model is filling unrealistically fast during casting simulation (under 1.5 seconds for roughly 5-6 lbs of aluminum to fill a small cross-section mold cavity). If anyone could give advice on if my pouring cup is too big or if I've got a setting configured oddly, I would be willing to send all of my information.
