Questions about Translation Costs and Automation in WPML

Thank you for your message. However, I would like to receive a comprehensive response, as the settings and assumptions for my website depend on this clarification. Currently, I have over 5,000 products, and the plan is to translate the site into more than 15 languages. Therefore, every word matters.

To ensure clarity, I have broken my questions into distinct sections:

Question 1: Translation Costs for Text with Variables
I have prepared a fixed product description template, with certain attributes being replaced dynamically.

Example text:
*This collectible diecast model car by [Manufacturer] is an impressive [Scale] scale replica of a [Brand] vehicle from [Year], meticulously crafted with high-quality [Material]. This model, in [Condition] condition, is perfect for both seasoned collectors and passionate car enthusiasts.

Designed with exceptional attention to detail, this diecast model captures the essence of the original vehicle, making it a standout piece in any diecast car collection. Whether you’re expanding your [Scale] scale model car collection or searching for a unique gift, this meticulously crafted model offers authenticity and elegance. For your convenience, the product code [Product code] ensures easy identification and reference.

Don't miss out on adding this exceptional model to your collection today!*

The attributes in square brackets ([...]) are dynamically replaced with values such as 1/18, Metal, or specific brands like Ferrari.

Here’s my key question:

If the [Scale] attribute only has two options (e.g., 1/18 or 1/43), will WPML calculate the cost for the entire sentence each time, or will it recognize that only the attribute is changing?
Similarly, for [Material], with two fixed options, will it reuse translations instead of charging credits repeatedly?
The most significant concern is [Brand] and [Manufacturer], which might have 20 and 40 variants, respectively.
If [Brand] and [Manufacturer] appear in at least 20 and 40 different combinations, will WPML:

Charge credits for translating the entire sentence every time?
Translate the text once and reuse it based on memory for all combinations?
Calculate costs based on all unique combinations (e.g., 20x40)?
In summary, what would be the cost of translating this text if [Brand] appears in 20 versions and [Manufacturer] in 40?

Question 2: Translation of Identical Product Titles
When translating products, I currently do not translate product titles, so WPML displays them in their original language.

For example:
Product Title: Rolls Royce Phantom VII EWB Diamond & Black Kyosho 1/18
If the title remains the same across all languages, will WPML consume credits to process this translation?

Additionally, does the same logic apply to:

Product titles
Image alt texts
Other identical metadata (e.g., slugs)?
In my opinion, no credits should be used since the title remains identical across all languages (e.g., "Rolls Royce Phantom VII EWB Diamond & Black Kyosho 1/18" in both English and French). Please confirm if this is correct.

Question 3: Partial Translation of Product Titles
If I decide to translate product titles, such as:
Original Title: Rolls Royce Phantom VII EWB Diamond & Black Kyosho 1/18
Translated Title: Rolls Royce Phantom VII EWB Diament & Czarny Kyosho 1/18

This translation only changes two words ("Black" → "Czarny" and "Diamond" → "Diament"). Will WPML:

Charge credits for the entire title?
Only charge credits for the translated parts?
Furthermore, if the word "Black" appears in another product title, will WPML:

Use translation memory and not charge additional credits?
Charge credits again for translating the same word?
Final Request
Please provide a detailed response to each question, as these answers will directly influence the website's development and cost estimation.

Thank you in advance for your support!
