Total Power Budget 83W but total load maybe 100W at power-on
Hi all, we plan to use Netgear GS305EPP for a new project. This has 4 PoE ports with a maximum power budget of 83W.
All 4 PoE ports will be connected to a PoE device that can use up to 25.5W but average usage is only 10W or so.
So possible maximum at start-up or power-on is 102W with average total power usage of 40W.
Is our use case OK for GS305EPP?

Somehow you mixed up the specs of the unmanaged GS305PP (max 83W) with the GS305EPP (max 120W power budget).
Either way, I'm with stuart012broad : If your project requires more than this - even in a small margin - the PoE controller might refuse powering the fourth powered device requesting 25.4 watts.
Look for the GS308EPP instead. It won't kill your hardware budget - and you are on the safe and the supported side with your project.

Probably yes. There is a max 120W power budget according to the GS305EPP data sheet.
PS Sorry, I had a 100W power budget in my head when initially replying here.
The Netgear GS305EPP has an 83W PoE budget, while your worst-case startup draw (102W) exceeds that. Even if average use is only ~40W, at boot or peak load the switch may shut down ports, stagger power, or fail to power all devices.
