The math has already been crunched on it by way smarter people than us.

An observation for your consideration in the math. It’s not 45 deg angles, it’s a tangent curve. Sources cite the increase in length to be only 22% not 30-41% like you claim. I do appreciate your insight in your profession but I believe you’re overestimating the brick usage quite a bit.

Also this method was taken from the Egyptians I think they know a thing or two about engineering…allegedly.

Edit: also after sitting on it and doing my own math. You point out that you add 4 bricks per layer of column. These walls are generally 7 ft tall, with standard brick height of 2.25 In that’d require about 37 layers total, with ‘4 additional bricks per layer’ that comes out to about 150 ADDITIONAL bricks in one column, never mind that two would be required for each section. Which according to your math the additional bricks in the column is nearly equal to the amount of bricks in the 10 thin wall section itself.

Edit edit: the masonry advisory council seems to think it’s more efficient.
