Has anyone used the PowerPlay Table Generator to overclock/undervolt a Radeon VII

With no announcements of Big NAVI at this year's CES, I'm looking to swap my 1080Ti for a Radeon VII.

I'm coming from an Aorus GTX 1080Ti Extreme Waterforce. It's a great card - fast and silent with AIO cooling, but I'm sick of the buggy NVIDIA web drivers that make my system unstable. Now with no NVIDIA Apple's future, I'm ready to move on.

Researching the Radeon VII, I came across a series of posts from a user in Germany who made an Excel spreadsheet that's a PowerPlay Table generator for the Radeon VII and allows parameters for overclocking, undervolting, and fan curves to be set and injected to the card via Clover.

Users are reporting performance under macOS exceeding the 2080Ti in some benchmarks using this tool.

Has anyone here tried tweaking PowerPlay tables on the Radeon VII or other AMD GPUs? Any advice or experiences much appreciated. Thanks!
