Until recently I did the following such calculations ‘by hand,’ but I recently realized that ChatGPT can reliably perform these calculations accurately and much more quickly than I am manually able to do so.

Remember also that during Trump 1.0, AI wasn’t much of a thing.
Here are the results of my AI-assisted research:
