IoT Central rules triggered each 10 instead of each two seconds

Question

I have a rule, when a value is bigger than x it should be triggered.
The rule is fired approximately every 10 seconds.(The Logic App run every 10 seconds, for 450 milliseconds to 1,43 seconds)
IoT-Center get the data every 2 seconds, so the rule should be fired every 2 seconds the value it get is the same all the time.
From the Docs to IoT-Center: "Without aggregation, the rule triggers for each telemetry data point that meets the condition. For example, if you configure the rule to trigger when temperature is above 70 then the rule triggers almost instantly when the device temperature exceeds this value."
SO it should work, any Idea why it don't work?

If I use Event Grid from IoT-Hub in Logic App it work well every 2 Seconds.

Answer 1

I think i had Deleted the Question.
I found out that the is limitaion One alert every 10 seconds per action.
At first I was read "Tutorial: Create a rule and set up notifications in your Azure IoT Central application"
And from theier I remember that it should be fired evry Time it get Telemetrie data.
I also rember about "There is a limit of 50 rules per application."
But i didn't find anything about the limitation.
