EventRateLimit on kube-apiserver is not being applied - kubernetes

Question

EventRateLimit actual configuration which is not working
Version: K8s v1.23.10
kube-apiserver daemon
/usr/lib/systemd/system/kube-apiserver.service
...
--authorization-mode=Node,RBAC \
--client-ca-file=/var/lib/kubernetes/ca.pem \
--enable-admission-plugins=NamespaceLifecycle,NodeRestriction,LimitRanger,ServiceAccount,DefaultStorageClass,ResourceQuota,EventRateLimit \
--admission-control-config-file=/var/lib/kubernetes/admission-control-config.yml \
...

On kube-apiserver logs, clearly shows how is correctly loaded
Oct 04 11:16:09 master1_enc kube-apiserver[1560]: I1004 11:16:08.995589 1560 plugins.go:161] Loaded 12 validating admission controller(s) successfully in the following order: LimitRanger,ServiceAccount,PodSecurity,Priority,EventRateLimit,PersistentVolumeClaimResize,RuntimeClass,CertificateApproval,CertificateSigning,CertificateSubjectRestriction,ValidatingAdmissionWebhook,ResourceQuota.
I'm testing my config with hey tool the following way:
creating many jobs
./hey -q 25 -c 2 -n 200 -H "Content-Type: application/json" -H "Authorization: Bearer XXX" -D ./job.json -m POST https://127.0.0.1:6443/apis/batch/v1/namespaces/default/jobs
-q 25 means 25 requests per second
-c 2 means 2 workers at the same time (basically 50 request per second)
-n 200 means 200 requests
hey tool result:
...
Summary:
Total: 4.0073 secs
Slowest: 0.0319 secs
Fastest: 0.0037 secs
Average: 0.0059 secs
Requests/sec: 49.9093
Status code distribution:
[201] 200 responses #<- 200 requests with http code 201 returned
...
THE PROBLEM: The test should fail, based on EventRateLimit config should accept only 2 requests per second, but is accepting much more, completely ignoring my config. What could i be doing wrong?
