in thread Average random depth formula required

A chance of 0 means your average depth is going to be zero. If you are counting the number of coin flips instead of the number of wins, then you need to add one to the result ;)

That odd number should probably be 1/e = ~0.367879441

    Right you are, I do count the "wins" ^^.

    1/e is a nice guess (theorized it myself in some point),
    but the number I mentioned is very accurate (just doesn't include many digits so..).
    bty, 1/e returns an average of about 1.08 +- 0.0001, while the mentioned number gives an average of about 1 +- 0.0001.

    Any idea how to solve this thing ?
