The "stuff about boxing" has been discussed on the reddit thread, and I will have it fixed by tomorrow. Thanks for highlighting.

As to "Gc not being clever", the code is clear that it is intended to be clever in the long run, so the essence of the message could stay. Maybe the wording could be made more precise, thanks again for highlighting.

As to the "number of other wrong or slightly wrong things", I would be more than happy to fix the text if you have concrete remarks.
