I should probably explain some of the idiosyncrasies of the spreadsheet. If the driver didn't set a time then the time remains empty, as for the first few laps of most driver's times, or is designated as the same as their previous lap.
I don't know what would stop the driver setting a time, but I would guess they would go through the pits, rather than over the start/finish line.
This explains why there are groups of laps with exactly the same time. I guess they go out, come back through the pits, the car is checked for whatever reason, and they go out again.
The format is minute:second.millisecond @ hour:minute with the time after the @ being the time of day the lap was set which makes it easy to see groups of times. This allows you to see if the driver did a long run, or a short run.
As mentioned earlier you can see the drop off in times, presumably due to tyres. If anyone has seen this information elsewhere please do say as I know it's not in the best format, but it was put together very quickly as when I decided to do it the test day had already started so I wanted to capture the lap information as quickly as possible.
