By default, the autolooper will execute a swap when the amount that needs to be rebalanced within a channel is equal to the swap server's minimum swap size. This means that it will dispatch swaps more regularly, and ensure that channels are not run down too far below their configured threshold. If you are willing to allow your liquidity to drop further than the minimum swap amount below your threshold, a custom minimum swap size can be set. If autolooper is configured with a larger minimum swap size, it will allow channels to drop further below their target threshold, but will perform fewer swaps, potentially saving on fees.
