I've got the same 10 gal big orange Rubbermaid Cooler that just about everyone has on HBT. I've been hit or miss on more than a few of my mash temps. I use Beersmith and it gives me a ball park but it never equates for cooler temp because of the lid, sides, etc. As many of you know, the cooler will hold temp for easily over an hour without 1 degree fluctuation. It's just hitting the initial temp that's the problem.
What I'm proposing is a spreadsheet that tells you how much water at what temp will go into your cooler for your amount of grain. I'm proposing that we do everything in pounds/ounces and ferinheit. I'm also proposing that we do this with the assumption that your grain is at room temp and you have not preheated your cooler. I know it's easier to preheat but we'll have an inconsistant variable by not knowing how much you've actually added to your cooler for how long and and what temp to do the preheating.
I'll collect the data once it gets to a sufficient size and report in spreadsheet style.
Here's my first equation for the mild that I'm brewing today:
(7 pounds 11 oz) in 2.5 gal of 168F water = 158F Mash temp
(16 pounds) in 5 gal of 167F water = 154 mash temp
