did a step mash on alt today. went with 145F at 5.3PH for 30mins, then 158F at 5.45PH for 45 minutes. went pretty well, although first step strike water was hotter than needed, so will adjust down 3F next time.
interesting thing is my efficiency went up significantly. would have been 87-88% and came in at 96%. must admit I wasn't expecting that big a difference.
anyway-thanks for those who provided input before I ventured forward.
edit: seems perhaps increased efficiency is not so abnormal...must be what those of you who step mash experience.
