R^3 Accuracy help

[xxXitsunexx]

I've been using FFR's Velocity Engine for playing FFR for a while now and I've just recently swapped over to the R^3 engine since it has more features. But what I've realised is that every time I finish a song on the R^3 Engine, I get more Perfects than Amazings, and my accuracy is just atrocious; it's really starting to annoy me. A friend told me about adjusting my Global or Judge settings, but I'm not sure on what values to put in. Can anyone help me on this?

I play StepMania more often than FFR, so if anyone can help adjust the settings for the judgement to be similar to SM, that'd be awesome.

Thanks in advance
