Newly replaced battery Design Capacity dropping quickly

I recently purchased the MacBook Pro 13" Retina (Early 2015) Battery / New / Fix Kit IF123-054-5 and everything went really well in the replacement process, Ifixit’s instructions were incredible and really easy to follow, really happy.

Battery was at 100% Design Capacity as soon as I turned it on and everything works really well so far, but a few days and 4 Cycles into my replacement battery’s life, Design Capacity has dropped to 97.6%, which I think is a bit quick but I don’t know any better.

Design Capacity according to Coconut Battery shows as 6559 mAh, Full Charge Capacity is 6402 mAh.

Is this normal or is it deteriorating quicker than it should?
