99 is a gift. Probably within measurement error, as least for me. I got 99 today on the hydro & 98 on the refractometer once I corrected my scales. While it was once fun to measure all day long, and constantly lose temps, and extend mash times by a ridiculous amount and making my brewday 9 hours long I am going to get away from it. too time consuming. I'm leaning towards the table is good to correct a problem, but not needed every brewday. I think brewfun said your good to go if your hitting your gravities, and I am by .01. I get caught up in hitting perfection, and its just not gonna happen. Too many measurement flaws.
whats your measure method? I been using the strainer and eyedropper to pull a sample, it makes you stir the mash before sampling and its always low no matter what from the top of the mash, and always high from the drain port. so screw it. Its always in the sweet spot when measuring from the first run kettle.
My wife doesn't know anything about beer making except what I have driveled on about, and even she had the sense to say today, why don't you just go back to making beer? She should be in a book.
