Very interesting results, thank you.
xyem: These revealings imply that 2 of my posts in this thread became low-rated at some point, reducing my rep by 2 and then someone uprated them, possibly just to remove the low-rating.. which didn't restore my rep.
Why in this thread ?
"As I am not particularly active on the forums I can pretty easily check my posts and despite none of my recent posts that I've made in the last week or so that I can find being "low rated"..."
If your findings are correct ^^^^ this is an unreliable method of verification, it could have been any post including the ones in the last week.
Everthing seems to work as i thought it did, with the exception of
"Uprating to remove a low-rating does not restore rep unless it is uprated significantly."
a +1 rep is apparently not being applied to a post tha gets 5 downvotes (thus -1 rep) and subsequenyty gets 1 to 5 upvotes, as, imo, it should.
if 5 downvotes is the shifting point that determines a -1 rep subsequent upvotes, between 1 and 5, should restore rep to its orginal value.
A post fluctuating between -5 and -4 (in terms of downvotes and countering upvotes) a couple of times ends up being more punishing rep wise than a post that gets 10 flat downvotes and stays put after that. I can't believe this is intended behaviour.
In any case it seems clear that the system can't be messed with unless someone cheats.
Oh, I should be at 3198 actually, the 3193 i started out with plus 5 from a question topic that got closed just now on the BL board :)
