"To be fair it was ok. It wasn't the greatest lap of the weekend but it was enough to get us through," Martin said of the lap.
"At the end of the day it doesn't matter - we are starting in the right position."
The rain had eased a little bit by the time the shootout took place. With dry weather forecast for Sunday teams will need to adjust to the right dry set-up very quickly before the race.
"The first practice was crazy," Martin said. "Some places you needed a jet ski I think.
"I believe it is going to be dry [on Sunday]. In saying that we haven't really gone with a crazy wet set-up on the car - it is 50-50.
"I think the [Sunday] warm-up potentially could be the most important session of the weekend."
Teams will get a 20 minute warm-up tomorrow morning before the race begins at 12.40pm.
