It would be a low percentage but not near-on impossible, which is what you've been inferring. Categorically football just isn't as linear as that.
Not really sure it's that ironic? Millwall have yet to play Hull, Ipswich and Middlesbrough and have over the course of the season have proven they struggle against those in the top 6. As mentioned previously, one win and one draw out of 7 games.
They've had a great season, and are on a great run, but that 'micro-form' is what will probably cause them to fall short IMO assuming it continues.
