This is the reason the kelly's is not the best form of staking....mathamaticly yes it may be but emotionally it is not.....90% of punters could not handle what kelly betting offers when it cals for a bet of 20% of your bank on one selection and it losses then you can be sure that will have an affect on the emotional state of the punter....also to work the system correctly you need to be able to assess a horses true price....some thing that also 90% could not do......IMO the best form of staking is a bank percentage bet of between 2% & 5% of your bank depending on your SR and a recalculation of the betting amount at a predetermind level....this level can be anything from every 10 bets to say once a month....i would not suggest a recalculation every bet.
