DataStore - OnUpdate event limits?

The intention here is just to get a query clarified.

According to the Roblox Tutorial on DataStores, it is said that the OnUpdate() event has a limited request budget - along with all the methods - that is renewed every minute.

I'm planning to use single-player servers for this project so the limit is 35 requests/minute

Does that mean I can make up to 35 connections per minute? OR does it mean the sum of all the times all the OnUpdate events fire in one minute must be below 35?

Thanks in advance, dav1000999
