Also, I would say that those SOH numbers are not "normal" for a car with 37,000 miles. Whether they are messed up because of past treatment of the battery causing damage or messed up because past treatment screwed up the measurements, it is hard to say without more information. I know for my car, my SOH numbers have behaved as I would expect and I have no reason not to believe they are more or less correct.
To get an idea of your true SOH-C, bring the battery down to true zero and measure how many kWh you put back in as ETS suggested.
For the SOH-R value, I'm not sure of a good way to check this. One thought is to measure you acceleration times and compare that to values published by others. If the battery resistance is high, then you would expect to see reduced current capability and lower acceleration times.
FWIW.
