Not sure I understand, but one cycle can have multiple events. This can be seen clearly from logs as recommended below. > 2. What happens when I schedule above-mentioned event say at tick 100?

Everything that is not instantaneous is done by scheduling another event in the future. > 3. Is there any way to visually see the eventq?

Not fully visual, but makes it possible to understand everything with a bit of staring.
