Aruba 1930 PoE Budget calculation

I'm planning a setup and need some guidance on the PoE budget calculation.

​

I'd like to use the following access point types (besides some other PoE devices):

• Aruba AP11 "maximum power consumption (worst case)": 10.1W
• Aruba AP17 "maximum power consumption (worst case)": 13.5W
  

With probably one or more of following switch models:

• HP Aruba Instant On 1930 Rackmount Gigabit Smart Switch, 24x RJ-45, 4x SFP+, 195W PoE+
• HP Aruba Instant On 1930 Rackmount Gigabit Smart Switch, 24x RJ-45, 4x SFP+, 370W PoE+
• HP Aruba Instant On 1930 Rackmount Gigabit Smart Switch, 48x RJ-45, 4x SFP+, 370W PoE+

Are there any best practices regarding calculating the required power budget?

Or do I just need to satisfy: "accumulated worst case power consumption < PoE capacity of the switch"

​

Which would mean 19x AP11 (10.1W) = 191.9W on the 195W switch. Quite close, but this is also worst case power consumption, so I expect the typical to be less.
