Can you easily produce an example? It doesn't have to be real data,
but should have the structure (typewise) of the real data. I would
like to perform some measurements. For example, I could imagine that

l = []
for i in range(1000):
  x = random.randint(0,100)
  if x < 4: l.append(None)
  else: l.append(x)

might adequately model your problem.
