CO2 levels

Not entirely true...It will take some time until compressor do it's job and replenish used compressed air. This time is directly dependent on compressor damage state.
I don't see any problems with CO2 level droping almost instantly after boat surfacing. Ventilation of small subs, like type VII was, should be really fast process IMO...

CO2 is also peculiarly as when you hit 10% you have to surface or your crew will die soon after.

Not true at all...

In SH5 (or at least with TWoS) you can stay submerged until CO2 bar reaches 100% which is something like 30-48 hours depending of factors like bosun's passive ability to "calm down" the crew and used crew states (silent state - lower CO2 build up rate, battle stations and faster repairs- high CO2 build up rate).
Remember that 100% on Co2 bar simulates toxic CO2 level and NOT real percentage...

Unfortunately, SH5 doesn't simulate realistic drop in crew performances caused by oxygen deprivation but lack of oxygen will affect crew moral which also acts as fatigue, most of the time. Further on, crewman who is low on moral/fatigue points will not be able to perform some of his special abilities... For example, chief engineer will not be able to lead damage control team, bosun will be unable to "stimulate the crew" ect...

Once CO2 bar reaches 100%, the crew will die...
