F5-ADSP-APIS-L:"LAD" how many requests per unit?

Hi all, quick sizing question on F5-ADSP-APIS-L (API Security Local Edition, Per M Requests, Per Month).

Does 1 unit equal 1M analyzed requests per month, so Qty 10 covers 10M/month? And what happens when usage goes over the entitlement?

I couldn’t find the part number’s unit definition in the public docs, so any F5 confirmation would help. Thanks!
