Per-User API limit paid plans

Hey

I am currently developing and implementing a browser extension for our entire team to integrate it into our very old and very obscure ERP. Toggl was chosen because many people in our team use it so we want to make it better for them. Currently, toggl has passed our privacy and security audit as singular personal time keeping app that can be used on our work-related devices. There is no real workspace as toggl is an individual tool for per person time management (optional).

I have built a cross-browser extension with very aggressive caching, request limits and even implemented “timer starting” via DOM manipulation if extension is used on the toggl page.
However I still regularly hit the API limit with normal usage (switching projects a lot in an hour f.e.) Am I reading the terms correctly that the paid tiers have no increase of per user API requests? That would make this all futile and I seriously cannot wrap my head around this model. Even if we paid 10$ per month per user we would still be stuck at 30 API requests per hour per user?

Even an increase by 20-50 requests per hour would seriously improve automation potential of toggl, especially in the times of massive global shift towards workplace automation.
