Williams technical director Paddy Lowe has said both he and the entire team are "very disappointed" with how he 2017 season has gone so far.
Williams are fifth in the Constructors' Championship and, like last season, find themselves behind Force India as the 'best of the rest'.
Lance Stroll delievered a memorable podium spot for the team in Baku, but Lowe is not happy with the overall points haul.
"Definitely at the half-term report stage we’re not looking as good as we’d like. We’re very disappointed, the car is quicker than that points table would reflect," said Lowe.
"I think one of our biggest problems has been that we haven’t been scoring the points we should have done at the track with our speed of car. That’s for a number of different reasons.
"On top of that, we’ve seen a lot of variation from circuit to circuit. There are places that we significantly underperform and we really need to have a car that will perform more equally at different destinations, so that’s a big focus for next year."
