Weird, when people download they normally won't skip a certain part of a split file (people usually download a big file according to the sequence of different parts) but they do skip a lot on wupload, see my screenshot below as an example:
I didn't make mirror links on other filehosts for these files (and they are split parts of a big file), but look at part 2, no download, and look at part 1 and 3, six downloads and four downloads already! That's strange enough! I don't understand why people skipped part 2 and chose to download part 1 and 3 in the first place. But this thing happens often on wupload. >_>
Ahh... Have you heard about premium accounts dude?...
Premium account = 1 day 1 Download count
So if someone who have premium acc download your part 1-2-3-4 (in 1 day) you will get reward only for 1 link
