This was Brazil 10 Days ago.
My 2 drivers are of near-equal pace (removes variables of suppliers, car design percentage etc.) and one was on Hards for the whole race and one was on Softs.
Hards were stints of: 11, 12, 13, 12, 12 and 11. Wear was down to ~38% after 12 laps.
Softs were stints of: 8, 7, 8, 8, 8, 8, 8, 8 and 8. Wear was down to ~33% after 8 laps.
Weather was hot so push levels were low.
I've seen more occasions since where I had started off with the intention of running a split strategy (one on softs, one on hards) and the hard tyres being the better ones to be on so adjusted strategy mid race. Using both types of tyres seems the fastest overall but in what combination will depend on track and prevailing conditions. Typically, 2 stints on hards (one stop) have been pretty close with 3 stints (2 stops) on soft.
I think it was intended that the combination of softs and hards to make the best strategy would result in more action during the races for all tiers.
