Calculation of Overcommit is wrong

4.16 

Every time

https://docs.openshift.com/container-platform/4.16/nodes/clusters/nodes-cluster-overcommit.html

states:

Scheduling is based on resources requested, while quota and hard limits refer to resource limits, which can be set higher than requested resources. The difference between request and limit determines the level of overcommit; for instance, if a container is given a memory request of 1Gi and a memory limit of 2Gi, it is scheduled based on the 1Gi request being available on the node, but could use up to 2Gi; so it is 200% overcommitted.

====

Going from 1GBi to 2Gbi is 100% overcommit not 200%. 0% overcommit means you're within the requested resources. Going over with 5% would mean going to 1.05Gi etc. which means going over by 1Gi is 100%
