Hi - I’m so sorry I missed this response. So basically you just divide 1000 by the duration in milliseconds to get the FPS because of 1000ms being one second. So 100ms in Unity FPS would be 1000 / 100 = 10 And 120ms would be 1000 / 120 = 8 (rounded down)
Don’t apologize - I’m happy to help wherever I can.
