there are 2 theories on this.
#1 the disavow file is similar to a robots.txt file and Google doesn't count all the urls you submit.
#2 The disavow file is compared to all the disavow files submitted and those sites that are theoretically above a certain percentage level in all disavow files are eliminated. (This is the machine learning theory)
I suspect the reason we do not see a large percentage of people seeing recovery after submitting a disavow file is because theory #2 is the correct one.
