Thank you for some more information on this table
It seems the table on the web page has the incorrect headings on the
columns
if all the figures are shifted to the right one position it becomes
understandable.

Now for example Weight Kg/Mu becomes Harvesting Number and Harvesting
Number becomes Survival rate. now the survival rates do not exceed 100% .
and the weight Kg/Mu is as you quoted in the reply
