Okay, I guess I'll stop now. I don't have the book or know the methodology used, but if this is correct, it appears that Babe Ruth was able to hit multiple home runs longer than people can hit today, even with lob pitching in Coors field.
I still feel a little skeptical that someone was able to "list every home run hit by Ruth during his career, along with estimated distances that the ball flew in each case" without relying on possibly unreliable witnesses. I don't think the newspapers of 1918 were giving the exact details of every Ruth home run and I am pretty sure no one was filming every game he played. I know if someone showed me a tree off in the distance and asked me how far away it was I would be lucky to come within 100 feet with my guess.
But, again, I can't say the book is inaccurate.
By the way, I am also a member of SABR, although I have not written any books, and I will now go back to the threads where I post cards.

And I am sorry to say, this is my only Ruth card (or 1/4 of a Ruth card).
