Combine Retry, Curcuit breaker and delayed scheduled delivery - masstransit

Question

I am struggling hard to properly test this scenario and could not really match the numbers. Could you please verify whether this configuration is correct for the below scenario?
When the message comes to consumer first time, want to retry for these exceptions WebException, HttpRequestException, RequestTimeoutException, TimeoutException. And after this retries exhausted I want to redeliver these messages( only for the above exceptions) using delayed exchange with intervals first time delay 2 minutes, then 4 minutes and finally 6 minutes and after 3 times stop redeliver and push to _error queue.
I want UseMessageRetry() should execute only first time and not every time when the message get to consumer through delayed exchange.
cfg.UseDelayedExchangeMessageScheduler();
cfg.ReceiveEndpoint(rabbitMqConfig.QueueName, e =>
{
e.PrefetchCount = 20;
e.UseRateLimit(100, TimeSpan.FromMinutes(3));
e.UseDelayedRedelivery(p =>
{
p.Intervals(TimeSpan.FromMinutes(2), TimeSpan.FromMinutes(4),TimeSpan.FromMinutes(6));
});
e.UseCircuitBreaker(cb =>
{
cb.TrackingPeriod = TimeSpan.FromMinutes(1);
cb.TripThreshold = 15;
cb.ActiveThreshold = 10;
cb.ResetInterval = TimeSpan.FromMinutes(5);
});
e.UseMessageRetry(r =>
{
r.Incremental(2, TimeSpan.FromSeconds(3), TimeSpan.FromSeconds(6));
r.Handle<WebException>();
r.Handle<HttpRequestException>();
r.Handle<TimeoutException>();
r.Handle<RequestTimeoutException>();
});
e.Consumer<Consumers.ProductConsumer>(provider);
});
