Hi Machine Zero..... Any reason diff_23592 for the L3+  ?   Thanks

You can use this simple formula to find out your starting difficulty: Instance speed in MH / 1.4 / 1000 * 65536. Example for 300MH it would be 300 / 1000 / 1.4 * 65536 = 14043.42 which equals to -p diff_14043. To be on a safe side you can use next power of two integer value, which is: log base 2(14043.42) = 13.77 = pow(2,14) = 16384. Unless there is no particular reason please do not set your diff inside password string. The pool auto adjusts per instance difficulty to maintain a share rate of approximately 3 shares per 10 seconds.
