Since last December when I finally moved in to the top 1% of users, I
have been tracking my stats. Since that time, I have consistently
moved up in my place rank (then at 28688th place and I had completed
more work units than 99.306% of users).

By Aug 27th, I had steadily moved up to 15454th place - usually tied
with several other users, and had moved ahead of 99.667% of users.

All of a sudden, sometime between Aug 27th and Aug 29th, I dropped
nearly 200 places to 15645th place and ahead of 99.663% of users. I
don't understand as there has never been a drop since I started
recording this.

I realize this sounds like a minuscule drop but keep in mind that with
over 4.5 million users, that .004% drop represents more than 18,000
users jumping ahead of me in just a day or two.

Since yesterday, (as I type this it is Aug 30 @ 8:41am) I have moved
up 52 places and gained .001% point, so it seems we are back on track
- but I wonder what happened.

Ideas?
