Jumping values from gradings (kwpn etc)

[Navalgem]

2010: KWPN fokwaarde springen 130 93%
2010: Duitse fokwaarde springen 153 87%

Why the diff in values for same horse?

Also, if the progeny perf affects the values, surely a stallion could be great at passing his wonderful jumping genes on but never really show it unless the right mares were used and the right homes found for the products?

and if the above is correct...what a minefield!

The top index is calculated by the KWPN and the other by the Germans. Both have a high "reliability". Must be a nice stallion. What is its name?

It is the sadly deceased Lupicor H.
