Thanks for your fast reply Rich.
I've done about 15 starts, in summary:
Pearl: hit rate is of 250kg bbs is not bad ~40% but damage is mostly 0* on BBs, rarely 1* or 2**. Problem is B5N also use 250kg instead torpedo, distance of TF too fare away?
TF53: 6 times sub attack, 4x hit Lex with 4**** (1x sunk)
MCS & AP symbol same in combat display
B17 from Clarke bombing Kagoshima
Dutch Harbour - Midway now out of range for ac with range 4, so ship transfer to Hawaii needed instead of flying via Midway.
Enough with starts, starting playing turns now .
Re Pearl: Yes, TF1 is too far, range needs to be less than 1/2 of normal range to use torpedoes or 800 kg bombs I believe. When I moved TF1 to range of 1 (100 miles, although historical was 200 miles), the Kates use torpedoes and the BB loss appears to be quite historical. Also, too many Allied aircraft are flying CAP; if I put the P-40s on training, the number of aircraft responding on CAP drops to ~10-12 I think (actual was 8). So these are the changes I plan to make.
Re Lex: Still don't know why this is. I didn't change code for IJN subs against Allied capital ships. I wonder if we need to move Lex by a hex or 2?
Re MCS / AP symbols: do you mean the icons used to display an image of the ship? I think some of MCS and AP types do share the same symbol...
Re Dutch Harbor: Dutch Harbor is actually about 1900 miles from Midway. The latest map has them 1800 miles (18 hexes) away. So an aircraft with range of 4, shouldn't be able to transfer between the 2 bases.
Re B-17 bombing Kagoshima: Kagoshima is actually 1240 miles from Clark Field, and the latest map has it at 1200 miles, so it looks like a B-17 from Clark Field could just reach Kagoshima.
Great comments, keep at it!
