This is actually a common question… I will explain why this happens.
Your torrent client updates with the tracker to obtain the list of peers and update your transfer statistics once every 30 minutes. This will mean that you'll have about 30 minutes where everything stays the same, and then all of the sudden, the stats will update. If you're seeding multiple torrents, this can become a little more complex, because the 30 minute refresh period is based on each torrent individually from the time it was started.
So... This is not at all unusual.
I also see that your upload speed is not the greatest, which kind of confuses me because I'm very familiar with your geographical area (as you're not all that far from me it would seem) and your ISP, and I fail to understand why it is so slow. The only thing that I could think of is that you have their ultra lite package perhaps?
Anyhoo... Since it would appear that you're trying to do the right thing, before your torrent gets purged from the system completely, I'm going to use it to gift you some SBP to help get your ratio in check. This should help to give you a boost to where you ideally need to be. Hopefully, this will help to get you on your way.
