Williams chief race engineer Xevi Pujolar reckons Susie Wolff did a "good job" during her test earlier this week.
The Williams development driver was in action at the Silverstone circuit for the final day of the Young Driver Test.
Covering 89 laps, Wolff put in a best time of 1:35.093, which put her ninth on the timesheets, 2.199s off the pace.
"I think she did a good job," Pujolar told ESPNF1.
"She didn't do any mistakes, she didn't go off at all and I think she made good progress with the new tyres.
"I think to extract the potential of the new tyre she was missing a bit - similar to what we had with Dani [Juncadella] - these tyres, especially when we do the run with the mediums, if you don't get the first or second lap then you're using grip. By about lap four or five when they get more comfortable with the car the grip is not there.
"So I'm sure if we had more new tyres in the afternoon the performance would have been better, but we had just a limited amount of sets. I think she did a good job; it's difficult with these tyres just to get the lap one to get both axles together. For someone who does not have much experience in the car I think it's positive."
Pujolar, though, downplayed the prospect of Friday's test resulting in Wolff taking part in Friday practice sessions for Williams.
"That's not something that we've considered at the moment. The work we wanted to do here is different to what we do on a race weekend. We haven't considered that yet."
