The only reason to hold back is if you think you can hit your goal with cubes to spare. If you think you will spend every cube anyway, then your new limiter is time - whether you can spend every cube on a guaranteed L6 Megatron kill by the time the event ends. That is your maximum points potential. It doesn't really matter when you do this as long as you use every cube wisely.
