Okay, so, there wasn't a lot to go over but here's how you can make adjustments to this.
From my understanding of this piece, the AECT is to determine what scale the space coherency falls upon as read by the AECR. At least from my understanding. This is a pretty interesting way to create a more complex system to the ACS system.
The majority of the piece is consistent and covers all its bases. There are very few grammar errors but I'd like to note off the obvious ones.
"The remaining 37% consists of miscellaneous other tests and procedures."
You don't really need the 'other' here in this sentence. It makes the wording feel off and weird. Something like
"The remaining 37% consists of other tests and procedures that fall under the miscellaneous category."
"This is expected. In these cases, the abundance of other tests should still allow for an adequate coherency reading."
this might be me nitpicking here but it doesn't sound as fluid and coherent when read aloud. It could work if you reword it around a little like;
"This is to be expected in some cases, as the majority of the tests should still allow for an adequate reading.
"The The Anderson-Eckhardt Coherency Reader"
Remove the one 'the' from this.
Here's also some quote box to designate some shit that might need to go in these pieces. They're italicized.
The machine only makes use of several dozen sub-tests, meaning that /the// results are not very extensive.
Range like in mean, median, mode and range kind of measurements? I think you're going somewhere with this but you have to make it a bit more clearer.
Each approximation comes in the form of a range, with theactual ACS level falling somewhere within the mode of the scale.
And this is about as far as I got to tell you. Overall, I think it is a neat piece and a good addition to the lore that helps make things more clearer in how the ACS works.
