Bankroll Management Question

[jkpickett]

A friend of mine who has been a successful sports bettor for 3-4 years now seems to have a flaw in his bankroll
management and I wanted to come here and get some input. Basically he readjusts his bankroll daily and I contend his is giving up too much value by doing this.

His argument is that his method is more conservative.
He also argues it lets his winning streaks compound fully.

I countered him by saying he is giving up too much value on his winning days following losing days which happen much more often that long streaks. (bounceback days 55% or so, win streaks 9-11%)

Shouldn't you have a large sample size of plays before readjusting or do it based on a longer time because your low % of BR risked on each play is a built-in mechanism for avoiding BUSTO?

I could be wrong in my thinking, but I would like to take his method he's teaching me and tweak it according to a few leaks I feel he has, thus making me more profitable.

Hope you guys will give some good input (that's why I came here). Take care.
