This does not allow multi-stone suicide.   I don't
know the number in the other case.   

I just checked Lazarus again and it's getting
about 104.63 moves per random game from the 
opening.    There are some minor implementation
differences such as how suicide is handled,
the exact eye rule used, etc.

The heavy play-out version of Lazarus gets
almost the same number, but it's consistently
about 1/10 of move lower for some reason.

Are you trying to make a Monte Carlo program?
