Using multiple RateLimiters correctly. [Answered]

_hourlyRateLimiter = new FixedWindowRateLimiter(new FixedWindowRateLimiterOptions(
    200, QueueProcessingOrder.OldestFirst, 1, TimeSpan.FromHours(1)));
_secondRateLimiter = new FixedWindowRateLimiter(new FixedWindowRateLimiterOptions(
    4, QueueProcessingOrder.OldestFirst, 1, TimeSpan.FromSeconds(1)));
// ...
public async Task Test(int testNumber)
{
    var hourly = _hourlyRateLimiter.WaitAsync();
    var second = _secondRateLimiter.WaitAsync();
    await ValueTaskExtensions.WhenAll(hourly, second);
    Console.WriteLine(testNumber);
}

var tasks = new List<Task>();
for (var i = 0; i < 250; i++)
    tasks.Add(Test(i));
await Task.WhenAll(tasks);
