I posted this in the DRG thread, but it would serve better here:

Also for any of you wondering how SS scales with GCD, it's now 0.00037735 per point of SS. So you can do 2.5-((SS-354)*0.00037735)) to calculate your GCD. Alternatively, you can use this formula 2.5-(0.01*(SS-354)/26.5)) which should do the exact same thing, just a lot more accurately.
