Ratings decreasing

Help!  My ratings went down after I put an article up last night and re-structured another?   I suppose if people don't click on my articles this can happen, but I thought I'd query it anyway.  It came as a bit of a shock today to see I had gone down from 95% to 92%.  Doesn't give one any heart.  Shall I top myself or stay up all night writing another few articles?

(Thinks bubble).  Would it have anything to do with the fact that I deleted my picture (but I can't get the site to upload another).

Don't worry. Ratings can be up and down. Relax, sleep well, then get up tomorrow and write another enjoyable article.

Thanks, mate, will do.

So, I went to bed, slept well, did as you suggested, but today, my ratings have gone down another 3%.  Is this normal?   I've seen them climb since i started on here a year ago but to drop from 95% to 89% there must surely be something I should know.  Is there someone I could ask about my articles?  Are they not up to scratch, are my images wrong, are the subjects too banal (mostly travel i admit and it's not everyone's bag), but I never expected that my ratings would go down.  Up yes, but down ...........................?

Just before I posted this I returned to my pages to find, horror, that my rating now stands at 87%.

Help.

I don't really bother about my ratings. I'm more bothered about the amount of traffic that I have going to my articles. I have a few that sit at 30 something% but were doing really well for traffic, surprisingly.
