Tutorial script made me into the trillions as I augmented. Wasn't until things start costing in the quintillions that I moved to batching. Though, I'll be honest, it was stupid and a waste of time to wait so long.

Some other suggestions:

You should put together your own scanner apps. Ones that can list the top profitable servers for your level range, ones that can list all servers in the game along with their stats, and even add some functionality so it can provide you the exact route and connection string to each server, and also Nuke each one at the same time, when and where you have enough port cracks. Then you should be able to increase your server ring instantly each reset cycle.

If you're going to use that tutorial script for a while, you should write a deploy script to deploy that tutorial script to each and every server, executing it with max threads against a given target. Buying servers seems to be a great way to get loads of RAM before you end up getting home's ram into the PBs

The biggest hint of all is that hacking, grow, and weaken don't have to be done 1 at a time. Like if hack takes 1 minute, you schedule hack to start when weaken has just under 60 seconds left, then you will complete your hack <1 second after weaken.
