Never mind, aex. I found Kelly approximations (#2.1, #2.2, #3, #4) works most time. But I'm perfectly OK with optimal ratio that's based on numerical optimization. However, as I said above, the optimal value is much larger than 1, how could I apply it practically?

I did the calculations based on your posts:
