Some tasks are assigned with higher overlap (for example, “5”) and checked. The rest of the tasks are assigned with the overlap set for the pool (for example, “1”) and they are not checked. Selective review lets you improve pool completion quality. You can reduce the frequency of checking tasks over time. Example of settings: in the first 100 tasks completed by the Toloker in the pool, assign every 5th task with an overlap of “5” to check matching responses. In the following tasks, every 25th task is issued with an overlap of “5”.

speed_quality_balance. count	integer The number of active Tolokers the task is available to. The field is shown if the balance type is set to `BEST_CONCURRENT_USERS_BY_QUALITY`. May take a value from 1 to 100.
dynamic_overlap_config	object Setting up dynamic overlap (also known as incremental relabeling or IRL). Allows you to change the overlap depending on how well the Tolokers handle the task. Set the closing interval (`auto_close_after_complete_delay_seconds`). It should be enough to complete tasks with an overlap higher than the minimum. When all pool tasks are completed, aggregate the responses.
defaults.default_overlap_ for_new_tasks	integer The overlap for tasks that are uploaded to the pool (used if the `allow_defaults=true` parameter is set at upload).
mixer_config. min_real_tasks_count	float Minimum number of general tasks in a task suite (if the number of assignments left is less than the number specified in `mixer_config.real_tasks_count`). Minimum — 0. By default, the value is the same as in `mixer_config.real_tasks_count`.

Values: `true` — Assign an incomplete task suite. `false` — Don't assign tasks. This option can be used if you are adding tasks after the pool is started. The default value is `true`. This parameter only applies to general tasks. The number of control and training tasks in the last suite must be complete (`mixer_config.golden_tasks_count`, `mixer_config.training_tasks_count`).
mixer_config.force_last_ assignment_ delay_seconds	integer Waiting time (in seconds) after adding a task or increasing the overlap before assigning the last task suite in the pool. Minimum — 0, maximum — 86,400 seconds (one day). This parameter can be used if the pool has `force_last_assignment: true`.
mixer_config.mix_tasks_ in_creation_ order	boolean The order used to add tasks to suites: `true` — Add tasks to suites in the order in which they were uploaded. For example, in a pool with an overlap of 5, the first uploaded task will be included in the first 5 task suites. They will be assigned to 5 Tolokers. `false` — Add tasks to suites in random order. The default value is `false`.
mixer_config. shuffle_tasks_in_task_suite	boolean The order of tasks within a suite: `true` — Random. `false` — The order in which tasks were uploaded. The default value is `true`.

The interval bound is the number of a task in the pool. If the task suite has several intervals, the settings for the first interval are applied. Example: In the first task suite (the range from 1 to 25), every fifth task is a control task, and in the following suites, every 25th task is a control task.
mixer_config.training_task_ distribution_function	object Issue of training tasks with uneven frequency. This option allows you to change the frequency of training tasks as the Toloker completes more tasks.
