My interpretation of this section is that you cannot create 4k connections per minute. Here's how I might think about it: in ANY 1-minute period, you can create no more than 60 channels. For example, you can create 60 channels at time T. Then, over the next 60 seconds, you cannot create them. Or you can create 30 at time T. Then create a channel every 2 seconds.
I believe another way to think about this is token token algorithm .
In any case, I believe that you can fill out this form to request a higher limit. There is a link to this form from the documents that you contacted in your question.
