Do some pdf services require more units than others?

[Robert22788616336o]

Hi, I've been enjoying the PDF extract API, but I've noticed that it's charging me more units than I've been calling the API.  For instance, just now I made 3 extract api calls, but it cost 7 units.  Why?  Also, I'm currently doing the trial version that comes with 1000 free units.  I certainly don't want it charging me more than what I'm using it for when it begins to actually cost me money....

Thanks!

Extract uses one transaction per 5 pages of a document. All others are one transaction per 50 pages.

You can see the various transaction charges here.
