It is purely dependent on the nature of hydrological environment that you have been working. The charge and recharge would lead to these variations depending upon the flow in a given situation.

Seems to be related to the Time of Concentration of runoff and the catchment area, as well as initial extractions assumed for your model.

All the input parameters like time of concentration , curve number, initial abstraction etc. however, i somehow agree with @Ryan Good answer

The time step will influence how the input data in used. Ideally the simulation time step will be the same as the precipitation data interval. Using longer simulation time steps than the precipitation will lump multiple precipitation measurements into one calculation, which effectively averages out the precipitation rate over each simulation time step and reduces precision. Using smaller simulation time steps than the precipitation data interval will divide the precipitation data over multiple time steps and would show a higher degree of precision in the results than could confidently be modelled based on the input data.
