Azure Face API: Transcation per Person Group - Train

I am trying to pricing a project that utilizes the Person Group from the Azure Face API.
We got max 10k people in a group, therefore a Person Group is enough for us.
We have a requirement that needs to add new people in group from time to time, so it requires training quite frequently.

I am trying to find out how many transactions is required per training for a Person Group.

The closest thing I can find from Azure website is as below, however it is all talking about the "LargePersonGroup - Train". I need to know how many transactions count for a "Person Group - Train"

"For operations that enable training at million-scale (available beginning March 1, 2018), a transaction is counted for every 1,000 images trained. “LargePersonGroup – Train” and “LargeFaceList – Train” belong to this category. Each operation in this category is rounded up to the nearest increment of 1,000 images. For example, a “LargeFaceList – Train” operation that includes 849,500 images will be counted as 850 transactions."

    Sorry for the late response due to US holiday season.

    I just got confirmation from product group: a transaction is counted for every 1,000 images trained. “PersonGroup – Train”, “LargePersonGroup – Train” and “LargeFaceList – Train” all belong to this category.

    I have an alternative solution for your scenario may work, please check below document about Person Directory. A good feature for it is you do not need retrain your whole group so you don't need to concern the transaction fee.

    Hope this will help. Please let us know if any further queries.
