If Alex does as you claim, there will be _plenty_ of errors.  He has to type
one move every two seconds, with +zero+ time for analysis.  At that typing
rate, I'll bet most any amount of money you want that the book won't even
+parse+ cleanly, due to either his typos or typos in the analysis he is
typing madly...

Your math just doesn't stand up to even simple scrutiny.
