Horizon balance "auto" split queues

[AsemAlalami]

Why does Horizon split queues and run separate workers for every queue if the balance is "auto"?

public function createProcessPools()
{
    return $this->options->balancing()
                    ? $this->createProcessPoolPerQueue()
                    : $this->createSingleProcessPool();
}

protected function createProcessPoolPerQueue()
{
    return collect(explode(',', $this->options->queue))->map(function ($queue) {
        return $this->createProcessPool($this->options->withQueue($queue));
    });
}

I took a look how the auto-scaling works, and I have seen that it is already calculate the time/size for all queues at the supervisor

protected function timeToClearPerQueue(Supervisor $supervisor, Collection $pools)
{
    return $pools->mapWithKeys(function ($pool, $queue) use ($supervisor) {
        $queues = collect(explode(',', $queue))->map(function ($_queue) use ($supervisor) {
            $size = $this->queue->connection($supervisor->options->connection)->readyNow($_queue);

            return [
                'size' => $size,
                'time' => ($size * $this->metrics->runtimeForQueue($_queue)),
            ];
        });

        return [$queue => [
            'size' => $queues->sum('size'),
            'time' => $queues->sum('time'),
        ]];
    });
} 

so I don't know why it executes a separate process for every queue!

I need to execute processes based on the minProcesses and maxProcesses for all supervisor's queues not for every queue in a supervisor

Thanks
