Thanks for the term clarification and the conversion table, Craig. According to that table the amount of Cake yeast is more than double the amount of ADY. Lehman is using up to 0.75 Cake, so by my SOTP, 0.3 would be about equivalent, the same as I've already used for the 4 day CF.
JD, you're suggestion sounds rather high as based on the table and my SOTP that would be around 1.1%, though probably fine I think I'll go with .7 % and split the difference.
I realize it's all about experimenting and experience. Hopefully it will produce some pies worth posting.
Thank you both.
