In my experiences, medium tyres only work at mid 30 degrees or over on medium to high-speed circuits. I would never use mediums on Singapore as it is a slow twisty circuit that uses high wing level. Go SS to get track position at the start of the race then softs for your next few stints. I can only go off our 1 speed 100% distance experience. Good luck next time
You're spot on, but there is an exception that I've found...
I'm in a 50 percent league, and I've won on a 1 stop medium strategy in France, in temperatures as low as 13 degrees...
