Talk:Process window index

Issues
Just minutes ago I found in this article a passage that read as follows:

$$ \text{PWI} = 100 \times \max_{i=1\dots N \atop j=1\dots M} \left\{\left| \frac{measured\_value_{[i,j]} - average\_limits_{[i,j]}} {range_{[i,j]}/2} \right|\right\} $$

Where:
 * i = 1 to N (number of thermocouples)
 * j = 1 to M (number of statistics per thermocouple)
 * measured_value [i,j] = the [i,j]th statistic's value
 * average_limits [i,j] = the average of the [i,j]th high and low limits of the statistic
 * range [i,j] = the [i,j]th high limit minus the low limit of the statistic

I changed it to say this:



\text{PWI} = 100 \times \max_{i=1\dots N \atop j=1\dots M} \left\{\left| \frac{\text{measured value}_{[i,j]} - \text{average limits}_{[i,j]}} {\text{range}_{[i,j]}/2} \right|\right\} $$

Where:
 * i = 1 to N (number of thermocouples)
 * j = 1 to M (number of statistics per thermocouple)
 * measured value [i, j] = the [i, j]th statistic's value
 * average limits [i, j] = the average of the [i, j']th high and low limits of the statistic
 * range [i, j] = the [i, j]th high limit minus the low limit of the statistic

One lesson is that whatever it takes to get nominated to be a "Good Article", it doesn't required much attention to standard Wikipedia style conventions. Then I corrected two links in the opening section in which every word began with an incorrectly capitalized initial letter.

So now I'm wondering: why does every word in the title phrase begin with a capital letter? Michael Hardy (talk) 04:01, 26 December 2008 (UTC)


 * Hi Michael, thank you for the fixes and article review. The text was in capitals because I had initially thought these were proper nouns – at least in some of the books I have with me, they were. Now that you mention it, I did verify them, and have changed these to lower case. Regards, Zithan (talk) 15:06, 26 December 2008 (UTC)

Hello. When I said "the title phrase", I meant the phrase that is the title of the article: Process Window Index. Why do those three words have capital initial letters? Michael Hardy (talk) 18:22, 26 December 2008 (UTC)
 * Not sure. That's what the sources say. Zithan (talk) 18:37, 2 January 2009 (UTC)
