Yes. The "lead" of 286 is arrived at by taking the original margin of victory (261) and adding the +25 differential from the first count in the counties that have been recounted. That's what our sheet shows.
Our numbers come right from the WA SoS site.
(Is it possible that the numbers haven't/can't refresh on your copy of the sheet? Another Freeper had trouble with that earlier. One thing to try would be to click the "Refresh Data" button on the External Data toolbar (you might have to show the toolbar first). I wonder if the WA SoS site is overloaded. The spreadsheet automatically refreshes every 10 minutes.)
