Answer

on the mark = to be 100% correct
off the mark = not to be 100% correct

Variations of this are:
off the mark
far off the mark
very far off the mark
not so far off the mark (=quite close)
not too far off the mark
etc

Answer

"not so far off the mark"

so "not so far off the mark" means the experiment results were close to the mark.
in another way : Technical flows were very close to the agreed value.
