Everyone on pit lane in Canada during practice on Friday seemed to be working with one eye constantly on the weather overhead, and Force India admitted that this had very much been the case for them.
"Conditions were overcast all day," said chief engineer Jakob Andreasen. "The threat of rain keeping us on our toes and forcing us to adapt our programme to make sure we came away with the data we needed.
"That was why Nico ran the super-soft tyres this morning, just in case the afternoon turned out to be wet, while Paul focussed on the softs," he explained. "In the end the rain held off and we were able to run through a complete dry tyre programme with both cars."
"The weather was a bit of a worry today with the constant threat of rain so we had a very busy morning and probably did more laps in FP1 than we normally would," agreed driver Paul di Resta. "By the end of the day I was very happy with the feel of the car in terms of balance.
"Of course the ambient conditions are expected to change overnight," he added. "We need to see how that impacts us tomorrow, but based on today's performance I think we can target Q3 if everything comes together."
Di Resta's team mate Nico Hulkenberg agreed that it had "been a good start to the weekend" and added: "There is still a lot of homework to do this evening and room to improve things further."
Force India's technical director Andrew Green confirmed that the team had brought some upgrades with them to Montreal and that it was just the first step of a program designed to put them back into contention as the season nears the midpoint of the year.
"We're going to follow the same plan as last year, which is we'll continually bring new part to the track every race, as a strategy that we've followed before, as most teams do," he said. "We will deliver what we can, that's our target.
"There are updates here, there will be updates in Valencia, there will be a bigger one at Silverstone," he confirmed. "That's the idea. We'll keep pushing. It's incredibly tight and fractions of a second can mean multiple places on the grid. It's harder than ever. There's a big push back at the factory."
Green said a lot of the team's push for improvement was thanks to the drivers themselves, what they brought as individuals and how they were working with the team as a whole.
"They both work together very well. It's good that they both push each other. They're both very talented, extremely talented," he said. "It's also important that they're both team players. They know that they want to push the team forward, they're not just individuals, and they work as a team. We all work as a team pushing the team forward and they get pulled along with that.
"We're very very happy with the way they work. It's a nice place to be," he summed up.
