WINNING THE CONSISTENCY GAME – There's a handful of drivers who have avoided major fluctuation and ran incredibly consistent throughout the week, and might be some potential pole or Firestone Fast Nine sleepers considering how steady and fast they have been on their solo runs.

Panther Racing's pace has carried over from the past few years at IMS to this year with the new car. JR Hildebrand is another whose outright fastest lap doesn't match where he's ended each day – the sophomore Californian has ended anywhere from second to 13th, and ended the day over 220mph each of the last four, although his best lap is only 16th overall. Panther's new technical partnership with Dreyer & Reinbold Racing hasn't paid off from a speed standpoint to Oriol Servia yet – Servia has only once ended a day higher than 11th – but no doubt has the chops to pull some rabbits out of his hat and start in the front half of the grid.

Takuma Sato is one to note. The Rahal Letterman Lanigan Racing driver's best lap is only 18th in the combined charts, but Sato ended each day from Saturday through Wednesday between ninth and 13th, the last three days ninth overall, each in the 220mph range. He ran fewer laps Thursday but seems to have a solid handle on his car; teammate Michel Jourdain Jr. has been working to get up to speed in working with engineer Bruno Couprie.

Justin Wilson has also shown strongly in Dale Coyne Racing's No. 18 entry, in part at least due to his engineer Bill Pappas. As the two have been reunited for the first time since 2009, that car currently stands ninth among all entries at a 221.677 – fourth of the Honda contingent. Outside of Tuesday when he ran fewer laps, Wilson has ended the day between fifth and 12th on the charts. James Jakes, too, has shown improved speed even though he's been roughly two mph down on his teammate.

FREE AT LAST Although neither has been threatening the outright leaders to this point, Panther DRR and Bryan Herta Autosport are still substantially closer to the front of the field with their Chevrolet and Honda engines, respectively, after each ending their contracts with Lotus. Incidentally, the two cars driven by Alex Tagliani and Servia are next to each other on the combined speed chart to this point - 19th and 20th overall with best speeds of 220.703 and 220.643.

It's an interesting year for both squads. Panther DRR, of course, has downsized from four cars to one for this year's Indy 500, although the Panther technical alliance means Servia and Hildebrand are essentially teammates and able to share information. By contrast, BHA is no longer affiliated with any other team and back to striking out on its own, after running this race last year with a technical partnership with Sam Schmidt Motorsports. The team continues to make strides to match both Tagliani's pole and BHA's race win accolades of a year ago.

KV, SCHMIDT STRUGGLING – While Foyt broke out of this group with their Thursday runs, the trio of KV Racing Technology Chevrolets and pair of Sam Schmidt Motorsports Hondas have languished in the high teens and 20s all week. You'd have to think, in some respects, engineering is an issue.

KV's E.J. Viso, now sans Pappas tuning the wrenches on his entry, has yet to run a lap faster than 218.550mph, a full six-tenths of a mph off Ed Carpenter as the lowest in the 219 range.

KV's struggles aren't limited to Viso, though. Teammate Tony Kanaan has shaken down both his and rookie Rubens Barrichello's cars, and hasn't ran above 214mph in either of his handful of laps. Kanaan, with his longtime engineer Eric Cowdin back in the fold, has only had two days where he's ended the day above 220mph – and his best speed of 220.305 is just 21st. Barrichello's initial week on the IMS oval has been more about learning the nuances of the track, but it took him until Thursday to run faster than 217. His 219.432mph is just 26th on the combined speed charts.

The Schmidt squad – which secured three of the top six spots on the starting grid a year ago (two Schmidt entries and the technical partnership with eventual winners Bryan Herta Autosport) – has not been able to show the same pace of a year ago and the lack of Allen McDonald's presence is obvious. For all his success on the road courses, it's easy to forget this is still Simon Pagenaud's first oval race, and he's having to learn a lot in a short amount of time. Pagenaud and Townsend Bell have been consistent with their speeds, but neither has ended a day higher than 17th and haven't hit the magic 220mph barrier yet.

THE DRAGON AND LOTUS SAGAS – Until Thursday, the Dragon cars hadn't turned a wheel on track – yet in one day with Chevrolets, both of the Dragon cars had already eclipsed the best speeds of cars with their former engine supplier. In his refresher test, Sebastien Bourdais showed he hadn't forgotten how to drive an oval, although he hinted at a loose car, while Katherine Legge made it on track after a daylong battle to complete two phases of her rookie orientation battle.

It's become painfully apparent the only way both Lotus entries will race a week from Sunday is if there are only 33 cars. There's a 12mph gap between Andretti's fastest lap – a tow-assisted 223.676 – and Jean Alesi's best lap for Lotus, with a boost increase, of 211.516.

Alesi, for what it's worth, has shown he can handle an IndyCar and has exceeded Simona de Silvestro's pace every day thus far. That speaks highly of the Fan Force United team, led by Tyce Carlson and with big engineering help from Tim Wardrop and Greg Beck. Unfortunately, both are hamstrung by the powerplant, and unable to make miracle gains overnight.
