What does the API Cap limit do?

What does the API Cap limit?

My assumptions are:

• For Radarr: 1 API call is a request sent to Radarr to search for the missing/upgradable item. I.e. 1 API call is 1 at Huntarr then 1 at Radarr then N at Prowlarr then (N*M) at Indexer, where N is the number of indexers used and M is the number of title variations searched.
• For Sonarr: the same but done on a per-season or per-episode basis (depending on your Missing Search Mode and Upgrade Mode)?

My questions:

1. Is that right?
2. Is the API limit I should set only dependant on the limits on my Indexers and not on anything else such as the *Arr backend SkyHook service?
3. Do I need to take SkyHook in to account as well?
4. What about if I have "Skip Series Refresh" and "Skip Movie Refresh" turned on? Is this still a thing? It's gone in 6.5.8.

Updated for v.6.5.8

I think I can answer several of your questions.

1. Don't know exactly. A dev familiar with the code would have to clarify these.
2. Yes, the limit is related to Indexers.
3. No.
4. Those skip features did not work as intended and were removed.
