Do want i do
If the anime have 25ep to download and you are using utorrent
Go to the file label , select the first 10 episodes and set High priority
The rest set as "Skip Dont download" , when the first 10 eps are downloaded , Set as normal that 10 episodes , and the other you put in "Skip" set as high priorty and so
Do that , depends of your conection or the seeders , is more fast in this way, cuz when you downloaded the first 10 ep , you can watch it and the other cap are currently downloading
Hope you understand =P
