Breathe Easier

UPDATE: V 1.5 * Intended ONLY for use with GJC's Bigger Crew Sizes. For a version based on vanilla crew sizes, head over to : https://steamcommunity.com/sharedfiles/filedetails/?id=3312625205 * Update to match current Live Patch * SURPRISE UPDATE! * Altered air usage from last version. * Type IXs with max crews should have a submerged time of roughly 10 hours, 58 minutes, no POWs considered. * Type VIIs with max crews should have a submerged time of roughly 12 hours and 23 minutes, no POWs considered. * Type IIs with max crews should have a submerged time of roughly 15 hours and 35 minutes, no POWs considered. * Note that because all three hulls have the EXACT SAME STARTING AIR AMOUNT, it is impossible (using only datasheets) to set all of them to around 12 hours. I have balanced this around the largest crew size that GJCs mod makes available at the time of release, so the II is going to have a slightly longer (though not overly unrealistic) submerged time. Watch those batteries, boys! - USAGE - The mod requires a new game and a clearing of the game cache for the air quality changes to take effect, based on feedback. Sorry - not something I can directly affect as best I can tell. -SUMMARY- Brings more realism for ship submerged operations time and performance of the potassium filters used for atmospheric regeneration. -THE WHY- First, it is important to understand that the AIR QUALITY meter is NOT an OXYGEN meter. Think of it more as countdown to unlivable levels of noxious gasses such as - predominantly - carbon dioxide. The crew passing out and, if not dealt with, dying is not due to lack of oxygen, but from hypercapnia (CO2 buildup). The vanilla game is setup to give the ship roughly six hours of submerged operations time before this happens. Historical records, however, clearly indicate that the expected submerged time was closer to eight to twelve hours. Since the game has a very simplistic way of modeling this - a single atmosphere meter that encapsul
