Dutching
A precise tool.
What is the Dutching & How does it work?
Dutching is a betting technique that spreads a single total stake across multiple selections so that the payout is the same regardless of which selection wins.
The core idea is to allocate more money to the longer odds and less to the shorter odds, balancing the implied probabilities.
Mathematically the stake for selection i is calculated by the formula below, ensuring a guaranteed profit when at least one selection wins.
\[ s_i = \frac{T \cdot \frac{1}{o_i}}{\sum_{k=1}^{n} \frac{1}{o_k}} \]
s_i = stake on selection i, T = total stake, o_i = decimal odds of selection i
