Edit:
Never mind, I answered my own question while playing around with it.
Glad you figured it out. I didn't know.

Once I saved the recipe it changed to the correct temp.

Does this method accurately predict your starting temperature for you? It worked well getting my volume close, but the temperature was way off. It predicted ~163F for a mash of 152F, but my temp dropped less than 5 degrees so it took me awhile to get down to where i wanted to be. Did I do something wrong or is it my process?

Well I also have to stir a good bit using this method. I don't have good notes to say what the temp is after stirring in the grains the first time. The temperature has never come out too low which is a good thing.

My starting temp was pretty close. Maybe you need to change something in the BIAB profile?

Can't find that brings the strike temp down. My numbers come out similar to what the OP has in his screen shots, so I think my profile is the same. If nothing else, at least I can get a volume from this method.

Check the "Mash Tun Temp Loss" setting in the mash profile you are using. This value gets added to the strike temp. So lowering it will lower the strike temp. I have mine set at 3F. I like it high because it forces me to stir a lot to get the temp down to my correct mash temp. Stirring more is good for efficiency.

Ok I see what you mean. Mine was still at the default of 2 so not enough to bring me down. This was only my first batch using this setup so I think I need to do a couple more to get a better feel for it. I also see your point about stirring I'm sure that helped me get a decent efficiency.

Thanks to the OP, I had been trying to figure out a way to do this when I stumbled on the thread!
