Has anyone done the math for figuring out PLL Probability?

To narrow down the probability here's the only OLL algorithms that I use:

1) R' F' U' F U R (x1) (x2) (x3)

2) R U' L' U R' U' L (Niklas)

*Special thanks to Werner Randelshofer for his Java Applet...*

Some common PLL algorithms after my OLL seem to be:

- J Perm

- U Perm

- Z Perm

- T Perm

- H Perm

At the moment when I'm faced with a PLL case that I don't know I just do a J Perm and another algorithm in the list above to solve the cube. In theory it'd be faster to just do one short algorithm instead of two.

I don't know all PLL algorithms so I can't identify the other common cases after

*my OLL method*. Knowing the exact probability would allow me to selectively learn few more algorithms to try to get near 20 seconds

Any help would be greatly appreciated!

Tim.
