In effect this is not a simple bug, since it originates from the original manual (page 53 of Feb. 83 edition).
At page 53 of the LE manual the Average tons of rice should read 6.20, instead of 6.40, being the result 6.202.
Since this mistake is also in the 1983 version, I suppose it was not corrected and simple OCRed into the new version, but I could complain about a missing verification...
My 2 cents for Felix Article.
Please, verify for yourself.
