The default retry policy is an exponential interval policy set to retry 4 times

An exponential series of numbers is one that doubles each time, for example, 1, 2, 4, 8 ,16. The value increases very quickly because every step is more than double the sum of all the steps that proceed it

To know the value of a 4 step exponential series you need to know the starting number and frustratingly Microsoft doesn’t tell us what that is! The timing for the default setting isn’t clear nor whether the setting is the same for every action

Consequently, it’s worth changing the Default retry policy and instead use one of the other three options. I’ll look at each in turn
