A 64GB instance in Azure is $156.28/month reserved. That's $2.44/GB/month.
Let's say you use an extra 4GB RAM for a safety margin or laziness, and you have 50 replicas. That's $488.375 per month 'wasted'. Or $5860/year.
You'll never recoup the money it takes to get those replicas perfectly sized. Just give every app 4GB more RAM than you think it needs, and move on with your life.
