wyeast propagator directions

So i made my first wyeast propagator starter per direction on the bag. It called for 8 cups water and 2 cups DME.

I thought to my self that this is a big starter for a normal gravity beer. Midwest's Honey Weizen. I made it to the directions and i ended up waking up to a big mess. It had fermented hard and came out the top of my flask and there was a sticky slime all over.

Are there any good resources where i can determine cell count based on started cells and size of starter. Or is the direction from wyeast the way to go?

Check out Mr. Malty to determine pitching rates.

And check out my calculator to figure out how much DME you need to make a starter of the size recommended by Mr. Malty.

Mr Malty Pitching Rate Calculator

This is a good estimation calculator. Without a hemocytometer and microscope, it is all just educated guessing (and even then, it is a bit of an estimation).

so it seems i needed 1.35 litters insted of 2 so my guess is wyeat rounds up just incase your brewing a higher gravity beer. From what i have read for us home brewers it doesnt hurt to have a bigger starter.
