I do question what size a jumbo mouse is. It may be a little too big. If your snake is gaining or losing weight you may need to adjust either prey size or feeding schedule.

I'm guessing you have an android phone. You might find an app called "Time to Feed" helpful. Maybe not, but at least I want you to know about it.

Most of us use a digital kitchen or postal scale to weigh our snakes and keep a record of their weights. I also weigh the prey. That's how I know exactly what is going on. The other ways to judge is to make sure your corn snake has a nice "loaf of bread" cross section shape. On mouse size under normal circumstances (not regurge) you want a mouse that is no larger than 1 1/2 times the diameter of the snake at the snake's largest diameter. We do this visually, so if in doubt err on the too small side.
