What do you expect the length of vect1 to be in this scenario? Seems to me the tstep value for your second case is just over 9 times as large as the step for your first case and the endpoints are the same, so the vector should be approximately 1/9 the length. What is 301/9?
Did you intend for final_time to be related somehow to the values in the time variable? That's not what you described.
