I've used my insulated mash tun multiple times now, and it works very well.

The only thing I haven't been happy with was the return. I finally settled on a stainless steel colander to help distribute the water evenly over the grain bed.

I had a keg lid left over from my last keggle build, so I trimmed it down to fit the Mash Tun, and secured it to the lid using two 6-32 stainless steel screws and nuts:


And then added the appropriate hardware to connect to the lid of the sparge return:


The Tee Connector will allow me to add a thermowell or sampling faucet.

We'll see how it works next time I brew.

Very true! Data collected for heat loss using just water is meaninglesss IMHO. A mash will behave very differently, and a large mash will behave differently than a small mash.

It has to do with thermal mass. The bigger the mass, the slower the heat exchange with the environment.

Yes, but I also feel that a mash is stagnant and will not thermally circulate inside the tun.

Sorry been a few years since I was schooled, so my terminology is lacking. Perhaps a mash acts more like a solid rather than a liquid?
