Hey Whiskey Brothers (and Sisters)!
I just finished building a new tool for determining actual proof based on the ttb.gov § 30.61 Table 1 Proof Charts. I have made the tool completely available for free and it works well on mobile phones, but if you want the data I request you make a 4.99 donation.
The tool is completely free and displays table entries within one degree +/- and one proof +/- which is required to conform to TTB proofing processes.
I wish I could make it all free but it cost me around $100 to get it transcribed using Amazon Mechanical Turk.
Hope this helps you, and any feedback is welcomed.
This is cool...good job
Nice job: Thank you for sharing this ..Chris
