I agree with you on that front, it frustrates me too. What he said is that Eddie did not alert to meat/foodstuffs in 200 cases operationally. He was during his lifetime, a very special dog who helped police secure many convictions and was also very effective in many other cases such as missing people who had sadly taken their own lives.
Picking up on Pathfinder's quote earlier:
Vol IX p. 2481
FALSE ALERTS
'False' positives are always a possibility; to date Eddie has not so indicated
operationally or in training. In six years of operational deployment in over 200
criminal case searches the dog has never alerted to meat based and
specifically pork foodstuffs designed for human consumption. Similarly the
dog has never alerted to 'road kill', that is any other dead animal. However, in his "personal profile" document, "searches" was missing:
POINTS TO ASSIST
Whilst it is stated that the E.V.R D. is originally trained using pig the following notes
of guidance should be considered when assessing indications:
P In six years operational deployment in over 200 cases the dog has never alerted to meat based foodstuffs.
> The dog has never alerted to 'road kill'That doesn't seem to be a PJ mistake, as the original seems to be in native English.

Grime may have added "searches" to "cases" in the report to clarify (there can be several searches undertaken within in an individual case), but the distinction may have been ignored. As, seemingly, was the fact that he was referring to Eddie's reaction to foodstuffs and roadkill.
