Next time just preheat the mash tun by using strike water that is hotter than you want by a few degrees. Pour in the correct quantity that Beersmith calculates and put on the lid. 5 minutes later remove the lid and stir well and take the temperature. It should be real close to your intended strike temperature if not right on that temperature. If just a couple of degrees over then stir until it gets to the strike temperature and then quickly stir in the grains. Put on the lid and check again in 5 minutes (Stir well before taking the temperature). It should be right on if the grains were at the grain temperature that you used in Beersmith's calculations. With practice you will be mashing right at the temperature you wanted every time.
