A quick ratio question

It's still pretty normal, especially for smaller torrents. No need to worry unless it gets more than 25-50%.

This topic comes up every now and again. I'm gonna weigh in on it because I notice another topic just started with similar concern, and I have an example where I'm missing over 11 GB of upload.
I've seen this before, I don't know why. It is real, although (usually) fairly minor. Usually I see that my utorrent (v 2.0.4 on WinXP almost always these last ~three years) uploads more than my tracker profile reports. It is not consistent, either. Some torrents track right down to the ~0.010 decimal place and I haven't run across any signs to let me predict.
Until recently, I figure it's just normal "noise" in the network. I run torrents for fairly extended periods of time, usually targeting a ratio of ~15:1 or up to ~20:1 for larger torrents (over ~5-7 GB). So, they may run for four or five months or longer, and may get deleted & reseeded in sessions a year apart, etc.
Anyway. Nurarihyon no Mago: Sennen Makyou [720p] [tlacatlc6] is one I reseeded from a D/L from Nyaa, except for a minor 336 MB of the extras which I had to download from here to complete the torrent as offered @BBT.
Looking at the absolute ratio on my tracker profile, I have uploaded 199 GB which gives 17.389:1 ratio (rounded to 17.4). However, my utorrent client records an upload of 210 GB with a reported ratio of 18.381. It's a full 1:1 hit to the ratio on that torrent over 756 H 2 min, according to the tracker. I consider under 1000 hours to be a fairly short seed time, BTW.
I mean, like I care personally. ::) My ratio is absurd, so I'm not affected. But, I can see how that might affect other people with slower connections and less OCD dedication to their seeding. Loss of 11 GB is a bit excessive for mere "noise" in the network. And, it's bleeding proportionally as time goes on. I didn't lose it all in the initial seed swarm. As time progresses, I see the ratio difference slowly increasing. Been watching it for a few weeks now, and utorrent also reports zero hash fails for zero wasted transfer in the statistics.
Other torrents, like I say, are all currently within much closer margins.
For example, this is far more typical of what I see when there is a discrepancy: Lone Wolf and Cub | Kozure Ookami. Here's one I've been seeding for half a year, both because it's below my ratio goal and because it has few seeders, so I'm trying to help keep it up with a healthy seedpool.
On my tracker profile it shows 125.17 GB upload for an absolute ratio of 14.256 (rounded to 14.3 in the tracker, and a 'relative' green ratio of 14.262). On my utorrent client, it shows an upload of 126 GB for a ratio of 14.398. This is almost exactly typical for torrents that I seed for extended periods (4359 hours at this moment) to higher ratios. A total of 3 hash fails for 12.1 MB in all that time.
THAT is what I consider loss to "noise" in the Internet.
Occasionally, BTW, I see it in the other direction, too. Sometimes my ratio on the tracker is slightly higher than the ratio reported by my client, although that has always been very minor ... never an issue of several extra gigabytes.
I don't have any handy other examples, but it has seemed to me that in the last year I have noticed a bit more loss in seed credit than I did in the first year and a half that I was here. Also, I do a fair bit of reseeding, which makes it much more difficult to directly observe these discrepancies.
As said, I'm just posting this for further information. It affects me not at all. But, I will support the reports that sometimes there is the odd torrent that drops a few GB of seeding ratio. It's more easy to observe on larger torrents that run over an extended time period, especially to higher ratios. When I've noticed it, it also seems that a particular torrent will act this way while others don't, and the loss is proportional over time rather than one or a few specific events. Tracking with BBT, I rarely ever see hash fails, BTW. one of the beauties of a private tracker that only allows its own server to be included in a *.torrent file.
Overall, I've found the tracker to highly accurate, probably within 0.1% or better nearly always. But I have seen a few odd burps in the system over time and over 1000 torrents. The other comments posted here are all valid as far as I've observed. I find that adding a torrent to my client shows up nearly instantly in my tracker profile, like within 30 seconds. However, when I Pause or Stop a torrent, it often takes 15 or 30 minutes for it to go Inactive on my profile. I consider that normal behavior for any tracker I've used; it should wait a while before making a torrent inactive just to compensate for normal network noise.
Also, if there's an abrupt & 'catastrophic' termination of the torrent ... such as power loss to the computer or the hosting service getting cut off suddenly ... the torrenting client doesn't get a chance to send a 'Stop' signal, so a torrent on your tracker profile may appear to be active for two or three days. I've seen that when I've been caught in a blackout a few times now.

I too have torrents that I've been uploading for close to a year now, actually 3 of the 6 I have right now are torrents that have never left my client since downloading. I will say that I have noticed the "inaccuracy over time issue" as well, but not nearly as pronounced. My own personal ratio is quite high so I'm not really worried about it dipping any time soon either but I'm slightly OCD and it bothered me when the numbers didnt match up. If there's nothing we can do about it, I'm cool with that but I just wanted to bring it to the attention of the staff, just in case this is a serious issue =]
For my part, I'll just keep seeding away; in the end what matters is that I seed and people use it....the ratio is just a bonus visual representation.
buchno:
When the tracker is down for backup each night, you upload during that downtime and then close the client before the tracker is up again so that the client can't tell the tracker how much it has uploaded, what happens?
megido-rev.M:
BTW I noticed that backup happens around 10-11pm ET and around 1-3am ET (can't quite remember precisely).
