If you were to divide files on the ed2k network in 4 categories, say 'fake', 'porn', 'recently released' and 'other', most of the files in the 'other' category will likely have little sources. Since almost all the files I download fall into the 'other' category and thus have little sources and they are all set to 'auto' priority, they all get 'auto(high)' priority.
So what's the problem? I am too lazy to set priority myself

It is my understanding that downloading rarer files with higher priority will result in an overall faster download of the whole set of requested files. Since all my files are set to high priority automatically this advantage is lost.
Proposal: no longer set download priority based on a hardcoded boundary (<50 or >100 sources for high and low), but calculate boundaries instead based on the file that has the highest number of sources.
