Those guys don't need number 2 especially not when going upwind. They have way to much experience to need telltales.
Also many times the "sweet spot" is not defined by the telltales. You "feel" it when the boat
hits it and speeds up (and points better)
I raced a unirig Cat for 5 years and didn't need them and don't have anywhere near the experience those guy do.
I'd sometimes be trapped out forward of the front beam also making the boat point and the telltales would be pointing almost straight up
