On stock motors without "hot" cams, both usually happen well before redline.

Physics police!
Vehicle acceleration is directly correlated to horsepower, not torque, so maximum acceleration is obtained by shifting to maximize time near peak horsepower and not torque.
acceleration = power / (mass * velocity)
It's not until the 3-4 shift that you'd want to shift at less than redline for peak acceleration, at least in a stock SC.
