Pay Back First
From EMule Wiki
If a peer has uploaded more to you than you've uploaded to them and the peer is on queue, then the peer immediately gets pushed to uploadlist. A Pay back First slot falls in the Powershare class (equals same priority as powershare).
Conditions:
- Payback First only works on completely downloaded files. (Morph mod)
- You have to pass a certain threshold for this feature to work (typically close to 1 chunk. = 10 MB)
