EarlyAmateurZymurgist... thanks for posting those calculations. You answered a similar question I had on my latest in-progress Kolsch using Wyeast 2565 that has a similar profile to the one mentioned by the original poster.
I mashed a little cool (accident/my first attempt at all grain) at somewhere around 148F.
My OG was 1.044 and my SG after 9 days was 1.003.
Copying the calculations mentioned earlier that gets me to around 74% attenuation.
Nice to know that its all moving along as planned!
