This PDF is extremely basic. Essentially what the creator did was take the suggestion table from the core rule book "Economy of your world" chapter and apply it to every equipment/consumable/item in the book. So yes it is ever so slightly easier to determine prices because you dont have to check if this tier 1 weapon is more on the 1 handful or more on the 5 handful side in value. As for the "Additional costs" those are one to one copies of the books table including things like a meal for the whole party or fine clothing. Do not expect to find any other things a party will ask for ("How much is this rope?"). So yes, a small help, but not worth 10 bucks. The text you wrote for each section does not help any GM with what they want to accomplish with this PDF. And distribution of the pricing and creation of the tables could not possibly have taken you longer than an hour. I suggest GMs just create their tables themselves instead of busing this.
