大家有冇一個難忘既情人節呢?
今天開始放大假,稍為有時間寫返小小分享。
近日甚少留言,工作忙得緊要。昨晚跑完馬做了檢討,自己的選馬系統今季成績差到極,已輸了過四萬元。輸錢感覺固然不好,但輸了長久 ...
19 win out of 37 races.
51% win rate
avg odds = 2.57
min odds need to make profit for 51% win rate = 1.96
and I found out 2 races odds is under odds 2.
should we should count 17/37
= 45% win rate.
then avg odds is 2.17
as the avg odds is too similar with the actual odds calculate from win rate..
even u use kelly.. the result wont have big difference if u bet fix amount each win.
