How do you count pages for MT in Productivity Services?

In the Productivity Services panel, Smartcat tracks the 3rd party services used during production, in this case OCR or MT. Tracking OCR pages is simple, processing one page in a PDF will deduct one page from your balance. But MT is tracked differently as words are counted. For this purpose, we assume 250 words per page so if 100 words are used for MT, 0.4 page will be deducted from the Productivity Services balance.
