Nit: Given that maxRetries is 3, we can never reach max backoff of 10 seconds. :)

Ah ok I originally stole that from here and just modified it along the way. Is a 1-second MaxBackoff ok?

It's ok to keep it as is. If you choose to use 1s as MaxBackoff, that's fine too. I think it's more important to do retry here, than how much time it waits.
