iBrewmaster does calculate the proper strike temp for single infusion mash. The trick is to avoid losing temp to heating your cooler. To do this I heat the strike water to iBrewmasters temp + 10F. I add the strike water to my cooler and let it sit for 15-20 minutes with the lid on. I then open up the cooler and stir until the water drops to the proper strike temp. Then I add my grain stir and hit my target.
Since lots of stirring is good for efficiency I add 3F to iBrewmasters strike temp. I do this by setting the field "Mash Tun Temp Loss" in the mash profile to 3F.
When i add the grain I stir the mash until the grain bed temp is at my desired mash temp.
If you are really good you can set the "Mash Tun Temp Loss" to include the temp lost from heating the cooler. I don't do that since the number will vary by season since I store my mash tun in the garage. If you keep your mash tun at a constant temp (in the house) this may work pretty well.
