How to ensure the stability and reliability of UDI calculation results in Ladybug/Grasshopper?

Hi everyone,

I’m a beginner with Ladybug and Grasshopper. Following online tutorials, I’ve successfully calculated the Useful Daylight Illuminance (UDI) for my project. However, I’m unsure how to ensure that the UDI results are stable and reliable.

I would really appreciate any guidance, check methods, or best practices to verify the accuracy of my calculations. Thanks a lot in advance for your help!
