All answers to this question require you to use a datapack to change something:

1. If you want to add a new tier between faulty and basic such that it upgrades earlier, you can create a new ModelTier.
2. If you want to make all models upgrade from faulty to basic faster, you can override the basic.json to reduce the required_data.
3. If you want to change how fast a specific model upgrades to basic, you will need to override that mob's data model and change the required_data.
