Night combat and Allied signint

[wpurdom]

My two issues with the early performance of AE in AI games are:
(1) My experience agrees with those who say the Jap navy is underperforming in night combat prior to 12/42;
(2) The first few turns, Allied intelligence was awesome - like many on the boards I knew to intercept the mission to Tarawa with the Louisville, also Legaspi with the Asiatic Fleet and Jolo with the Dutch ships. Massacre of transports, only had to pay a price at Legaspi (which was worth it). Doesn't Allied signint need to be tuned down until April 1, 1942?
