easier semi than the 1st seed.

Why is this?

The 2nd seed also has the 8th seed in the QF (while the top seed has the 6th.)

So 2nd seed has easier SF and QF.

(Also, Murray, the 3rd seed, has the easiest 4th round match. vs 16th seed.)

I would have thought semis should be 1v4, 2v3

And QFs 1v8, 2v7, 3v6, 4v5.

So why does the 2nd seed have an easier route? (In the 4th round, I admit, it's 1v14, 2v13, but the QF and SF are easier on paper.)

Or am I being really stupid.
