Please note that as usual in a running recap format, I'll post the latest news first. 
(A "warmer" update) The latest I've heard on when they will run is 11-something, although there are cars on the track now under a "running yellow" condition.
Here is the final chart, Dan Wheldon got a good tow in the last 15 minutes to pass Danica for 3rd. For Dixon and Hornish to run that much faster than anyone else, you also have to expect some drafting help there as well. As it was, the final 20 minutes looked like a Happy Hour run to me, and the resulting goose bumps on the back of my neck served to remind me how special this place is.
Also having good results today were Kosuke Matsuura and Eddie Cheever. Andretti Green Racing had to be disappointed with their results today, at the end of the session there was Tony Kanaan with a pretty good tow, and yet his best speed was only 13th on the chart. More ominous for AGR is their pit road position today, set in the same manner as IndyCar sets pit road assignments everywhere but Indy. IndyCar uses collective results to assign pit road position, and one of the reasons AGR found it easy to win in the past was those pit road assignments. Today AGR not only was behind MTP and TCGR, but the Fernandez cars of Sharp and Matsuura as well, and that's how it will be for Motegi.

This is the 4:30 chart, about 90 minutes later than the one below. As you see, speeds continue to climb. The test will end at 5:00 PM and then I'll post the final numbers. Last night at TCGR we confirmed one thing and learned another. What we learned is that they planned to be serious about challenging MTP for fast time of the test today, and with Scott Dixon topping the chart at this time, it looks like they meant what they said. The "confirmation" was about the teams having to use the engines from the cars raced at St. Pete for this test. Last night the TCGR crew worked late taking those engines from the street race Panoz cars and put them in the Indy Dallara's. As you can see, one is atop the chart. I guess once you put the cover over the engine it doesn't know where it is, so it doesn't matter. Dixon has run nearly 175 miles on that engine today, and it ran more than 200 at St. Pete, that's pretty reliable.

I have been out and about all afternoon, I made my promised appearance in the short chute and the turn two spectator mounds, and CCF posted the evidence. Then I went down on pit road and I think a real scoop in talking with Michael Andretti, at least I hadn't heard this before. I asked Michael if he was going to run any this afternoon, Michael said, no, "that he was going to run his car with Marco in ROP." With Michael out of a car for a couple of seasons, he may have had to do a refresher test anyway. With the possibility of the session ending soon, I thought I would post this mid-afternoon T&S chart to use for comparison purposes in ca we get some last minute flyers (which of course we did, as speeds are now above 225 mph). I still have no reason to suspect there is some sandbagging going on.
