while it is always fun to play with these things the problem is really interpreting what the results really mean ... monetary inflation is one thing ..that is where the money supply has expanded so much that the equivelant dollars is the ending calculation ... but only a portion of that answer is monetary inflation ... the rest is simple supply and demand ... if we over use something as a society and the price goes up , that is not monetary inflation .. if we stop over using the item the price falls .. look at oil , we paid more 10 years ago then today because that which was scarce is now abundent .
if oranges go up from the frost in florida that is not monetary inflation , if strikes , political issues ,politics drive up prices , that again is not monetary inflation even though the price went up .
you really could not look at a dollar in a particular year and say what the equivalent is because price changes by demand really should be adjusted out , we did that to ourselves by over use not printing dollars
