No not really it matters on cap too. Cap changes if the fighters are at 100 feet they are most likely strafing ground targets.
I look at my fighters and cap them at the alt where they start losing agility. For exampe the p40e losing most of its agility at 16k feet so I set it to 13000 to 15000 so it can dive on bombers and escort fighters. Works for me the early war Allied planes have to be given the ability to counter the nimble Japanese fighters and alititude is about all I have. The Betties come in at 13k and drop for torpedo runs and my fighters have plenty of altitude to drop on them and scatter them hopefully.
But that's what confuses me. I'm playing as the Japanese versus an allied AI, and I have been looking at altitudes set during the historical first turn to try to learn a thing or two (newb here). All the Betties that dived on ships, including the Repulse/Prince of Wales, were set at high altitudes, like 15k. But obviously they dropped to 200 feet once they got to the hex to drop their torps. By contrast, the Zeros slated for airfield attack on Pearl were preset to 100 feet. In other words, why am I not required to set my TF-attacking Betties at 200 feet for a torpedo attack while I AM required to set my AF-attacking Zeros to 100 feet? Is it me, or is there an inconsistency there? Am I setting altitudes for the journey or the attack itself?
