BTC 3 enrollment eligibility

Hello,

a company wants to join Bridge to the Cloud 3 next year.
They are starting with 40 users and then scaling up to 120 users after migration.

For the migration phase, they want to book 10 CSP users before joining the promotion. 

How should the following passage from the FAQ be interpreted?
Are 10 users compliant for the preliminary project because they are scaling up to 120 users, or only 4 because they are only booking 40 licenses at the start of the promotion?

Q3:
Can customers who licensed a small quantity of Dynamics 365 online licenses for testing enroll in this promotion?

A: Use of a free trial offer (prior to BTC3 enrollment) does not impact eligibility for this BTC3 promotion.
Although customers with prior paid online licenses of the same product are normally ineligible for this promotion, as an exception, such customers are not excluded if their peak number of paid Dynamics 365 online full users to date does not exceed 10% of the number of full users that will be licensed at BTC3 enrollment.

Thanks in advance!
