The maths behind slowing in turbulence to reduce G load seems logical. On the Airbus 320 /321 though there is the anomaly of turbulence penetration speed ( granted thats for severe turbulence )being 275Kts for the 320 but 305 Kts for the 321( basically the same wing but of course heavier aircraft ).It means you actually have to speed up in the 321 rather than slow down. Wondering what the logic behind that is ? The Mach number for turbulence penetration is the same at M0.76.
