Deep analysis paying off for Haas

Haas team principal Gunther Steiner believes the remainder of the Formula 1 season will still be "a rollercoaster" despite a "deep analysis" of its recent woes proving successful.
Since the remarkable start to Haas's F1 debut season - which began with two top-five finishes - its form has fluctuated.
Understanding the Pirelli tyres, and how to identify and exploit their correct operating window, has been key to this.
Romain Grosjean's seventh in last weekend's Austrian Grand Prix, where the temperatures changed greatly between qualifying and the race, suggested Haas's tyre efforts have paid off.
"We've now a better understanding of the tyres, and we've shown that over the last few races. We can predict with a bit more certainty what will happen," Steiner told Autosport.
"That has been the main focus of our race engineers, to find out when the tyres work, where do they need to be temperature-wise to work. A lot of work has gone into them, a lot of deep analysis to understand them more."
The ultra-soft continues to be Haas's Achilles heel, with both Grosjean and Esteban Gutierrez unhappy with the car's performance on the softest compound in Austria.
Gutierrez described it as "a bit confusing" and "not very nice" in qualifying and Grosjean said he "cannot get 100%" as it gives insufficient warning of when grip will break away.
Neither driver used the ultra-soft during the Red Bull Ring race.
"That was a choice, that was not by default, because we struggle to get that one to work when it's cooler," Steiner explained.
"In theory, an ultra-soft should work when it's cooler. It's the softest tyre we have, but we cannot get it to work because we are not getting it in the window to work. Maybe it would have worked, but we didn't want to take the risk. We know what we can get away with, but we didn't want to take any risk using the ultra-soft."
Such issues are why Steiner feels it is too early to claim Haas has cured its tyre understanding problems.
"It will still be a rollercoaster for us this season," suggested Steiner.
"By no means are we perfect, and the midfield is so tight with McLaren, Toro Rosso and Force India. Any of them on a good day are faster than us, but any of them on a bad day are only a little bit faster, but the car was pretty good again in Austria, so it will help us."
