French 8" turrets had dispersion problems, IIRC, so obtaining 4 hits in one salvo would be exceptionally unlikely.
Long range 8" gunfire produced a ridicolusly low amount of hits. Battle of Komandorski Islands (1943) produced 0.37% hit ratio for the 2 Japanese cruisers and 0.45% for the US cruiser engaged. The first hits were scored 10 minutes after the battle commenced.

A thing to take into consideration though would be that Graf Spee did have and did use a gunnery radar, and that was the Seetakt of 1940 vintage. It could track a battleship at 25km with a range accuracy of 0.5%. The initial devastating salvos fired on Exeter (hit on the 3rd salvo !) were due to the Seetakt radar. After the first 10 minutes, Graf Spee suffered several 8" and 6" gun hit on her forward structures, damaging both gunnery directors and main radar.
Even so, AGS crippled Exeter (out of action for 13 months and considered to be broken up for scrap), and damaged Ajax (6 months in repair and refit) and Achilles (3 months repair and refit).

I discounted the Radar firing control for the AGS based on Eric Grove's book (page 12), in a nutshell the "Seetakt" a 60 cm FuMG38G was effective to 15 km with not a sufficient bearing accuracy, the stereoscopic rangefinder was superior in bright hi-visibility conditions (13 Dec 1939). The radar was reserved for night and poor visibility.
thanks for the info on the german ORF, it is much better that what I have in the model and I will "upgrade" in my next release! It is not exactly a surprise due to the quality of the german optic industry.
