Simple script to calculate the error of polling multiple sample rates with Python `time.sleep`

	import time
	import numpy as np

	fs_list = [120.0, 2.0]
	dt_list = [1/fs for fs in fs_list]
	prevt_list = [time.time(), ] * len(fs_list)
	sample_times = [list() for fs in fs_list]

	timeout_seconds = 10
	sleep_seconds = min(dt_list) * 0.1
