lol, yeah, the ratio is messed up. It should be ~2.4. I swapped the input and output gears around.
Just take the reciprocal of the current ratio of 0.4167, which gives you the correct ratio of 2.3998080153587712982961363090953. Yeah, you can round that to 2.39981 if you want.
And if the ratio is different for the B vs the T, let me know. I add what people tell me and I assume they are correct.
