There is usually a delay from when the flash drives the data line (IOW, puts a data bit on it) and when the signal reaches the controller. This delay can vary by the flash, board, silicon characteristics, temperature, etc.
Temperature might change over time, but the calibration is only done once. I don't know how much influence the temperature actually has, but our boards are usually operating from -40°C to +85°C. So there might be a possible temperature difference of 125K between actual calibration and when the flash is accessed. -michael
