Note:
Split stake means when the stake entered in the Betting slip is split between the bet entries. For example, there are two bet entries and the stake is R20, then the stake will be split into two 20/2 = R10 per each entry. By selecting Split stake radio button you will make Split stake your default stake mode, but you will keep the option to switch between the stake modes in the Betting slip with Stake per selection mode.
Stake per selection means when the stake entered in the Betting slip is copied throughout all selections. For example, there are two bet entries and the stake is R20, then the stake will be copied per each entry, which makes Total stake 2*20 = R40. By selecting Stake per selection radio button you will make Stake per selection your default stake mode, but you will keep the option to switch between stake modes in the Betting slip with Split stake mode.
Stake per selection only is the same as Stake per selection mode but it will remove the option to switch between the stake modes in the betting slip, keeping the only Stake per selection mode.
