That's normal You can't draw conclusions from the health number. It's not a precise measurement, nor does it change linearly with time. It might remain at 94% for the next six months.
 
Keeping it always plugged in kills battery health. Some laptops have a feature to discharge the battery to optimal 50%, disconnect charging and run off of wall power to prevent battery degradation. I think Apple smart charging only caps the battery from charging up to 80%.

What does CoconutBattery say?
 
I have mine that after 20 cycles, has 91.6% (starting from 97%), as coconut says. Mac says 99%, instead.
