As a programmer, this makes me cry. I've written code and provided an osx binary to calculate the value from the provided formula:

How I use this last thing?

Um. Well, the provided formula is wrong, which might be why some people go through complicated calculations. That formula (which ignores quirks) should be (60*p+10*p^2) *(54/53)^p, since it's improperly pricing casting cost as written, and can in fact be entered into a spreadsheet in that form if you replace p with the name of the cell containing p.

The first thing I thought. Using Excel to write the formula, not a notepad or something only for text.

Actually I just updated the source code on my webpage, and it pulls the formula directly from the Magic text in the sidebar on page 20. I also calculated several trial values and they are very close to those listed (I suspect some rounding error in the text).

I didn't say that you inaccurately transcribed Magic; I said that your formula was wrong. The formula in Magic is also wrong.

Ah, you're sensitive. I'm one of those weird people who wrote his first, extremely simple, program before he ever used a computer (it had to do with dice), and designed my first webpage in advanced HTML without ever reading any instructions or asking anyone for help (I learned how to use the source function and went from there). So a lot of my stuff will look really, really crappy to someone who knows how to do it right; I don't care about elegance, just if it works.

And if that made you cry...when I ran a computer lab at an elementary school, we had no budget to hire someone to repair them. So I repaired one computer with masking tape and another with a paper clip. They were still working three years later. :-P

it not wrong, because they can only be used once in a blue moon due to recharge times. they are only useful for very special project that can be rare to take on.

Without powerstones, a 100 energy enchantment costs $3,300. With powerstones, it costs $60 plus the use of 6 7-point powerstones ($4,800 each, so $28,800). If you do ten enchantments of that size, the slow and sure method costs $33,000 (and 1,000 mage-days, or about 8 months for a circle of 6) the quick and dirty method costs $29,400 (and 2 months letting the stones recharge). This is ignoring powerstones on cheap materials, which wind up being cheaper than standard powerstones at any size larger than 2 points.

Umm you do know you can only use 1 stone mage right?
