I know folks are wondering if I'm just making this up. It seems too good to be true, which worries me also, so I decided to make a chart so I could see for myself. Here is a complete chart that shows all the leaders of 502 which I have mentioned above and, to be thorough as possible, I even went back a few extra weeks from what I normally do just to see if there was anything else there (there was). Here is the complete (to date) 502 Sync Chart. Note: The current draws are the left-most column and the history gets older as you go to the right. I had to truncate the dates to get this all on one page even using a tiny 10pt font. That's the best I could do, because it's a lot of history. Sorry. After looking at the final result, even though it's a little cramped, it's pretty easy to see how the syncs have been ticking along and then suddenly started piling up in the past week (see the bottom rows of the chart below).

And that's the long and short of it. If you look at the most recent draws down at the bottom, that's the stuff we've been tracking. I hope this helps folks visualize what I'm talking about.
