Characteristic curves for TX and PX in diafine

I was wondering if anyone has plotted out the characteristic curves for Tri-X and Plus-X in Diafine. I've been using Tri-X in it, usually rated around 1000 or 1250, and was wondering how it behaves being rated lower (say box speed to 800 or so). I know that Diafine can't help the speed defined by Zone I, but greatly extends mid tone sensitivity and makes it harder to block up highlights, but I was wondering what the curve looks like.

I can work it out, but I figured I'd check to see if anyone else had. Thanks,
