One of the biggest issuse with your amchecks is the amount you're removing. There's always a degree to the author's style that really should be included, and unless an analysis is completely chock-filled with fluff (such as
this one) there's little need in reducing the word count. I personally never remove too much and only focus on literal grammar mistakes. Whenever you make an edit in somebody's analysis, you have to ask yourself "Is there really something wrong with this section"? If not, I wouldn't think of making any kind of edit, as no writer wants to be told to rearrange their sentences one after another especially when there's not really an error. It also will discourage people from implementing checks. If anything, it's better to change too little than too much in an analysis, because there are always additional people that can find what you've missed, but nobody can bring back something deleted.
