Bug description

Incorrect average syncing speed
...

Steps to reproduce

1. Sync a dir with many files that require a long indexing
2. Wait for indexing to complete
3. Mouseover the setting box to read the actual transfer rate. It will show up a abnormal high speed (100 Mbits/s, while my connexion is only capable of 10 Mbits/s). This number will drastically lowers as the average calculation goes down.
   ...

Expected behavior

My suspicion is that the timer starts when the indexing is complete, but the actual syncing starts as soon as the indexing starts. The math is not correct as it should start counting time when the syncing begins, not when the indexing completes.
