Are you saying you slow by 70 knots for a Cumulus? Your approaches must be interesting. Or is this a slightly bizarre hypothetical example with no relation to what's being discussed or real world practice?
The point being made is that slowing by M.02 is not going to make any meaningful difference in ride. The advice is there to protect the structure of the plane in severe turbulence, in everyday stuff it really isn't necessary for that purpose, and will make no practical difference to the ride.
