```python
# Statistical performance analysis
text_times = []
for i in range(10):
    start_time = time.time()
    response = await client.post(...)
    end_time = time.time()
    text_times.append(end_time - start_time)

avg_time = statistics.mean(text_times)
meets_target = avg_time <= target["max_time"]
```

### Concurrent Testing

```python
# Load testing with multiple concurrent requests
async def make_request(request_id: int) -> Tuple[float, bool]:
    # Individual request with timing
    
tasks = [make_request(i) for i in range(concurrency)]
results = await asyncio.gather(*tasks)
