Sampling rate is not accurate (Arduino support package)

Hello everyone, I am using the Arduino Support package on Simulink to acquire an input signal and send the samples to workspace. The sampling rate specified in the 'analog-read' block is 0.01. This means that, when running the model for 20 seconds, I should expect 2000 data points (2000 X 1 vector in workspace). This is however not happening. It seems that Simulink is not collecting 100 samples per second. it would randomly collect a number of samples all of which are different than what is specified (0.01). Any ideas why this is happening? and how to solve it. Thank you. Here is a screenshot of my model.

If these are the only blocks in your model, then two more things to notice are sampling time of Workspace blocks and the sampling time of your model itself
