This is not just a question of free time. In case you hadn't noticed on the CurseForge page for GT5u, the license is "all rights reserved". This means I can't just pass around new builds like that. Afaik, only Blood Asp is authorized to put up such builds. Making one's own custom builds for personal use is generally accepted when source code is readily available (though perhaps not explicitly allowed by the license) as long as they're not distributed.
Also, I think what you're asking goes against the spirit of GregTech - if you cancel out the reduced efficiency from overclocking machines, what then is the point of using a Processing Array?
