Sadly, you can't learn much from a single number.
It's not really a measurement, just what the BMS thinks the capacity is from it's internal model. The number varies about +/- 1 Ah from one reading to the next. Also, you don't know what the actual capacity was initially. That, too, could be an Ah or two off nominal. So your battery may have degraded a lot more than you think, or not at all.
The only way you can track the aging process is to buyild the odyssey box, read the capacity regularly, and fit the data to get a trend.
