Most Common Use of Nulls in 15th Century Cipher Text
#2
It was Nick who commented about the supposed expected behavior of nulls. If I understood his comments correctly, we should indeed expect the removal of nulls to decrease entropy. It seems to me though that Nick was thinking more about relatively rare characters as nulls - relative compared to [y]. But I hope he will comment on this himself. That said, as I demonstrated it is extremely easy to decrease entropy by introducing nulls. This is not a complex operation, and it may be something anyone at any time could come up with. 

What I find most interesting - though I have not looked in detail at it yet - is Rene's study about which character has the highest information value in VM words. Combining this knowledge with null-hypotheses (  Angel ) may have interesting results.
