Differences between recipe strike water temperature and infusion tool

Hi,

I was playing around with the strike water temperature calculations that BeerSmith calculates.  I am currently running 2.2.1.2 (or 2.2.12... my eyes couldn't see if there was a period there).  When I created my recipe and selected the mash profile, it gave me a value of 160.9F for the following data:
  grain weight: 10.75lbs
  mash tun weight: 11.0lbs
  mash tun specific heat: .30
  current grain and tun temp: 72 F
  target temp: 152 F
  mash water: 4.4 gallons or 17.6 qts

However, if use these same values in the Infusion tool, I get a much high strike water temperature of 168.1.  Any idea why there is a difference?  Which one is correct? 

I have included a number of attachments to help someone recreate this issue.

First start by comparing apples to apples.  On your mash tab, select 'adjust temp for equip' and your strike temperature will come up to 165.6, which is still a bit away from 168.1, but closer.  Certainly, it does not agree and I cannot quickly see why.  Normally, I stick with the calculations on the mash tab, based upon my equipment file and don't use the stand alone tool, so I can't vouch for the tool's accuracy.  With my equipment profile and mash profiles, it works pretty well in the mash tab, and that is what I care about, since that is what gets printed on the brew day sheet and what I go by.
