Here's a strange thing. For the last couple of days, I've done a couple of practice laps then set my strategy, usually adding 1 extra lap. Then I'll go and do another lap or 2. Then I'll go back, just to double check I'm happy with my strategy. But here's the weird thing, the last 2 times I've done it, my strategy has changed, really changed, it's suddenly 10-15 laps short. Still the same tyre selection, as proof that I'd saved it, but a completely different number of laps.
