Wrong Ul/Dl and ratio

Looking at my upload/download stats, I noticed that they're wrong - according to my client, I've only dl'ed about 500MB. This, combined with a connection error that was keeping me from seeding that I didn't notice until recently, has totally thrashed my ratio. It's recovering now, but is there any way to fix the mistake?

do not touch mp3 until torrent shows 100% complete in your client. otherwise you can screw something or player will, so it will get stuck on 99.5 or will keep redownloading one little piece of 0.5% for ever giving extra snatches to torrent and screwing your ratio. watch it! it's only your own fault...

Say what?

i am not to sure,but my stats also seem to be wrong.i will investigate further and then decide if its really so.

slash is wright and if you ply a mix before it's 100% done it it will download forever i did once before
also when you try to play in your player you will miss litle pieces of the sound every few seconds
so be patient that's it  

still sometimes my client shows i am seeding 3 tor.and the tm shows only two?????

Oh, that's what he was saying. I couldn't really figure it out.
However, I didn't do that whole playing the file while it was downloading thing. Is there some other cause for that?
