Orders API rate limits

[MyGuyCai]

I am using the Orders().get_order('') end point to gather my sales for the day, I have a slight problem with the rate limit.

Here, in your docs it sates that the rate limit is 1 per second but
Here, in the Amazon docs it states that the limit is 0.0167 per second
And when calling the endpoint the returned rate limit is <'rate_limit': '0.5'>

What would be the fastest way to return all of this information? I have hundreds of sales a day I need to get the information for.

How do we know how many tokens are in the bucket for using burst requests?
