Three days might be fine at 68 degrees. Then, once there is no hint of diacetyl and the beer is at FG, it's fine to rack and lager.
You want to do the diacetyl rest when the beer is 75% of the way finished. That is one reason a correct hydrometer reading is so important at this point. A refractometer is totally useless at this point (less than useless, as it gives incorrect information once alcohol is in the mix, and trying to determine the time for a diacetyl rest).
