And here is the official video response from Robin of 8-Bit Show.& Tell, who was referenced in The 8-Bit Guy's video.

Slightly different approaches to table generation, lots of speedup, largely the same conclusion. Good stuff.

I found it ironic, that while he boasted his optimizations (which are indeed cool), he kinda swept the problem of the table generation speed - or the lack thereof - under the rug with some movie magic, by simply accelerating that part of his video.

But I'm also "cheating" - kind of. I had to solve this exact problem once for an embedded leetcode interview - "do a fast binary conversion but without a large table". Well, nibbles to the rescue. Then just reuse the generated nibble patterns.

I was told, this is what they use to fire at spaceships, that try to avoid paying the parking fee.

Either that, or it's the world's largest freely moveable tube telescope at the Archenhold Observatory in Berlin.

It was hard to get the fine details. I'm not a native German speaker. 🙃
