CO2 question

This may be a newby question but at what point does the CO2 level in the boat actually become an issue that affects crew performance. I often at the first sign of a patrol aircraft dive to periscope depth, set speed to 2kn and remain submerged until dark. At 2kn I will have plenty of battery to last all day but the CO2 warning usually comes on around midday. Is the downside of the CO2 worth the risk of surfacing in daylight to air out the boat?
