Okay, so as it stands, the Calculations Guides provides some general tips to pixel-scaling, however... I feel it missed some important bits. This was a fact I realized after approving a calc, but some images wind up using lines that are very thick, like 5 pixels thick, for pixel-scaling: https://prnt.sc/p0KeXiZjo56R
This may cause issues such as making something seem smaller than it actually is and blocking off important areas for assessment. I drew over the calc'er's pixel-scaling reference to analyze what his line would look like at 5 pixels thick and my preferred 1 pixel thick.: https://prnt.sc/o86vwunvi2dv
As you can see, using Y=413 (https://prnt.sc/Jx85tBJFhMJI ; https://prnt.sc/BvSHsuo5X_Js ) and Y=42 (https://prnt.sc/wVGmgfBgop6f ; https://prnt.sc/O-LE6ZvHjKgg ), the centerpoints used in the image, it is apparent that the five-pixel line is four pixels longer than the 1-pixel line. Of course in that part of the image (where the line is assumed to be 372 px), the difference is only 1.08%, but in another part, the difference is much bigger. At the same image using another reference point (one that is assumed to be 43 pixels long), the 4-pixel difference is much bigger: https://prnt.sc/7FeGnBNdMogx
I'm talking... 9.3%! Now, this isn't exclusive to this one calc. A lot of our calcs did that, and Dalesean even made that mistake with one of his calcs: https://vsbattles.fandom.com/wiki/User_blog:Dalesean027/Two_launches_a_tile_into_the_air
I think it has less to do with the members themselves and more to do with the lack of advisory info as to how to apply pixel-scaling on the wiki's end. See, the way to tell how big a certain line is on an image is by looking at the cursor and the size/shape indicator around the cursor (in GIMP's case, its this dotted-line thing with the pencil tool): https://prnt.sc/aX1yuhEnXnav
Now what Second22 (the calcer whose images I've used for my essay) did do right, however, is add a single pixel to the lines he made. See, in GIMP, the Rectangle Select Tool measures an image directly while the Pencil Tool's lines can be measured with an accuracy of -1 pixel. What this means is that a 20-pixel tall object can be measured at 19 pixels tall with the Pencil Tool.
As such, I think I shall propose additional guidelines to pixel-scaling.
In addition, I shall add some statements about Rectangle Select Tool scaling.
That should make it so that less "thick lines" mistakes are made in calcs. So yeah, there you have it. Hopefully this proposal flies with the wiki.

It is recommended that you use a line that is exactly 1 pixel wide when pixel-scaling for the utmost of accuracy. The 1-pixel line will also allow our Calc Group members to get a better look at the events that unfolded in the calc. Depending on the art program used, you may have to add 1 pixel to the measurement you've made in the case of a horizontal or vertical line, or use the Rectangle Select Tool to double-check in the case of a diagonal line. Drawing a right triangle can be used to double-check diagonal lines as well.
In addition, I shall add some statements about Rectangle Select Tool scaling.
Some programs have the Rectangle Select Tool, and in GIMP specifically, it can be used to directly measure objects. When using the Rectangle Select Tool for scaling, you'll want to make the rectangle you used visible enough for people to see, plus you'll need to show the Rectangle Select Tool's options as it shows the size in pixels of the selection. The reason for this is you'll need to screenshot the Rectangle Select Tool in action, as no image program can save the marquee provided in the Rectangle Select tool. An example of a screenshot used for Rectangle Select Tool can be found here: https://prnt.sc/4zOvXsyo0DMQ
The left number is for width (X) and the right number is for height (Y).
For larger images, a 1-pixel line may need to be used in conjunction with the Rectangle Select Tool for validation.
When using the Rectangle Select Tool to measure diagonal lines, you will need to start the selection at the start of the line, then drag it to the very end of the line. From there, you shall use the Pythagorean Theorem and apply both measurements from the Rectangle Select Tool to get the size of the line. For non-linear and non-square objects positioned diagonally, you'll need to draw a 1-pixel line across the object before doing so. In the case you need to measure a different dimension of the same object you measured (ex. an egg), make sure any other measurements needed are properly positioned perpendicularly to the line you just made.
