Have you taken into account capacity as a function of temperature?
Yes, absolutely. I have a temperature correcting SG hydrometer and a chart similar to yours for ah capacity vs temperature. I never really go lower than the thirties and recently not below 50. It's been around 60-75 lately when I've checked the batteries.
