Todd, if you are using something like BeerSmith, shoot me one of your .bsm files and I will look at it. 72.5% EIK is very low for a 1.050 brew and I want to ensure there is no misunderstanding or miscommunication here.
Having to wait a couple of years is now a thing of the past.
The thing about the BIABacus that might be hard to see is that you actually don't have to wait a couple of years at all to establish reliable efficiency figures. In fact, a brewer with a record of figures can immediately fine-tune the BIABacus. In other words, they will have a single profile that will work on all gravity brews.
This is impossible in any other software.
Just like a stopped watch is correct twice a day, any program that uses a profile with any sort of fixed efficiency figure is only going to be accurate in a few instances. In your case Todd, the 72.5% is only the correct
average for all the brews you have done. Let's say that the average OG of these brews was 1.050 then, if you use 72.5% on every brew you do, it will be correct for brews with an OG of 1.050 but too low for say a 1.040 brew and too high for a 1.060 brew.
Because the BIABacus adjusts efficiency according to gravity, all brewers have a whole new world of reliability open to them now. Firstly, the default auto-estimates are pretty good anyway so the BIABacus will be autimatically calculating an efficeincy figure that will get the new brewer in the ball-park no matter what gravity brew. Secondly, after a few brews, even if of the same gravity, anyone can easily fine tune the defaults to work well at all other gravities.
That's a very big breakthrough.
If you already have records, you can get 'back to us' immediately.
In the case where a brewer has kept records, they can actually 'back-test' a few brews 'on paper' in the BIABacus and see how well the BIABacus auto-estimate would have worked at the various gravity brews you have done in the past. In other words, you will be able to fine-tune the efficiency auto-estimates immediately and this should be a once-only task.
Other software will take you years.
Using
other software would take you years to develop efficiency figures that are reliable across a range of gravities. You will need to do many brews at many different gravities. Or, you could steal the BIABacus data. No matter which way you collect the data though, once you have it, you will then need to set up and use many different profiles to suit the various gravity beers or just be happy with using a single profile that works okay, on average. The BIABacus negates this need.
This is only one of the many 'profile' problems the BIABacus solves.
This 'efficiency' issue is not the only limitation of profile designs in other software. There are many. Here is another simple example...
If a brewer has a large kettle and sometimes does single batches and sometimes does double batches, they actually need different profiles for the two even assuming they always brew beers of the same gravity. In the BIABacus though, all the user has to do is change the 'Desired Volume into Fermentor (VIF)' figure in Section B. It's a two second task.
There are many other examples of how the BIABacus is not only safer, more fexible and accurate than other software but also faster to use. If you can adjust to some of the annoyances and minor inconveniences that occasionally result from the spreadsheet form we think you will be way ahead.
Looking forward to PP getting back. My fingers are worn out
