Thanks Connor.
I think that explains why my race in Malaysia fell apart today. I had practised in the dry, but saw this morning that it was raining, so I did one lap on wets to get some data. Then the rain stopped and although I was in time to change the tyres and fuel, I couldn't do anything to change the settings.
To be honest, it's frustrating, as once the fifth practice is used, there's no way to change the settings, even though race conditions can change right up to qualifying.
Anyway, thanks for your clarification.
