The 5000 Waits between the resetting of the Minerals and Gas isn't required. Since you've set it high so its not an issue, ever, i'd advise doing this.
Go through all the Units that you're create and set them to 0 for Minerals and Gas. Then you don't need that trigger because it creates them for nothing.
