同一場馬買幾碰W，怎樣分配注碼很關鍵。像四千幾那注，如變成二千幾就不妙了。有止蝕位嗎？

46%回報：主觀而言，這個回報率已非常好。因為小弟的合格標準是15%，30%為理想。

If one race with more than one selection, I would multiply it up according to horse no (that is by luck)

:) How about average bets in a single race?

If bet 4,000+ start from 20... range is so large and need to consider. But when it seems work, I have no substantial reason to say it's bad.

When you can afford to try, no harm. Good luck!
