For we math-numbskulls, what does this mean if you are correct? Does the oak-aging occur faster or slower than what the website says?

I'm mathematically challenged myself, I just noticed the number for a 53 gallon barrel were substantially different from what I had seen elsewhere.

I'm not sure where they went wrong in their calculations. The contact time periods may be accurate in relation to each other or the numbers may be so off that the data is uselessly inaccurate. If we knew the barrel radius and stave length for each barrel size we could recalculate all the numbers but I don't have that information.

you would also want to use the average Radius given that the barrel is not actually a cylinder
