Fix reporting burst limit reached when it was not

[p7g]

Not sure what the exact intent was with the old code, but it seems like it was reporting that the burst limit was reached every time the pool stopped bursting 🤔

After these changes it should work as expected, and it will only create the event once per time the pool is bursting.
