Bets that are triggered at the same time are sent in the same request (in batches). Due to the fact Betfair don't officially accept below minimum stake bets it takes 3 transactions. This option is to help with exposure problems when working with a low balance. For example 3 x £0.10 back bets has an exposure of £6.30 during the bet placement process when placed in one batch. If you changed this setting to 1 then each batch would have an exposure of £2.10 so it would work with a lower balance.
