Tongzilla - can i just confirm the spirit of yor thread - i think i know where you are coming from but just so everybody can confirm.
It seems to me that you are concerned with accuracy and precison of the science contained in the book - not at denigrating the work and effort that Homer put into TGM. In which case i am sure that Homer would not stand in the way of this quest for precision. It would be contrary to the stories that Lynn has told us about Homer!
If this is continued in a responsible manner i see no reason for there to be a problem. The problems arise when you do not know the credentials of the person who is supposedly "correcting" Homer! We know Homer's credentials and CV.... but if you are to correct Homer in such a way as to convince the audience then your credentials do matter. Not in the sense that credentials make you right... but they do make you convincing!
