I tend to agree with you Andy.
I found that 0.9600 was way out for my system and it wasn't until I selected "BIAB in the BS software that I achieved anywhere near accurate figures.
I think this anomaly goes a long way in peoples claims that the BM loses efficiency as the grain bill gets bigger. Simple fact is, people are using too much water to allow for grain absorption.
I have made adjustments on my software in this area over 40 odd brews and I have found that 0.6600 is pretty close to what I achieve.
Allowing the malt pipe to drain exactly the same each time is paramount in gaining the same result each brew.
Some sparge the grains, others don't. It will all go to giving you a different set of figures.
I know that some people just remove the pipe from the system without draining while some allow the malt pipe to drain right up until the boil is about to start.
I allow my malt pipe to drain after sparging until the boil is about to commence and I start the brew with 25 litre in the BM and sparge the balance of the volume as indicated by the BS software.
This is my method to achieve my set of figures in the software.
Cheers
