Simulink - average and output values

I use simulink to read from a sensor which outputs 10 integers values per second (10 Hz).

I would like to compute the average every 100 samples (each 10 seconds).

What is the best way to acquire the samples for 10 seconds and output the mean? For the moment, I'm using "tapped delay" function, but I do not know if it is working correctly.

I connected the "mean" block to the "tapped delay" block by specifying the "number of delays" to 100 and so I expect to see only 10 outputs after the "mean" block, but the values always changes and so I'm not sure if the output is correct.

Can you help me, please?

Configuration for the tapped delay block:

Configuration for mean block:

is there any suggestion?
