Limitations on nested VBCS Business Rules in HCM Redwood?

Hi,

We are configuring HCM Redwood pages, and our business logic requires us to write deeply nested Business Rules in VBCS.

Before we start building, I have a couple of quick questions:

1. Is there a limit to how many nested conditions we can add in VBCS?
2. Do highly complex, multi-layered rules cause UI performance issues?

How do you usually handle very complex logic in VBCS Business Rules?

Thanks!
