Hi @CabinfeverB. Thanks for your PR.

PRs from untrusted users cannot be marked as trusted with /ok-to-test in this repo meaning untrusted PR authors can never trigger tests themselves. Collaborators can still trigger tests on the PR using /test all.

I understand the commands that are listed here.

Instructions for interacting with me using PR comments are available here. If you have questions or suggestions related to my behavior, please file an issue against the kubernetes/test-infra repository.

In the issue， we can see the result as follows：

create resource group rg3 ru_per_sec=2000;
alter resource group rg3 ru_per_sec=5000;
2. What did you expect to see? (Required)
burst_limit = 2000

So why here is 6000 not 4000?

[CabinfeverB]

Sry, I wrote the wrong ddl statement in the issue. It should be
create resource group rg3 ru_per_sec= 5000;
alter resource group rg3 ru_per_sec=2000;
